摘要： PROBLEM TO BE SOLVED: To prevent the degradation of a viscous fluid stored in a heat generator of a heating device for a vehicle and to accelerate the buildup of heating capacity. SOLUTION: A control device 71 controls on/off of an electromagnetic clutch 51 of a heat generator 16 for a vehicle by compairing cutoff rotating speed variably set according to the water temperature Tx of engine cooling water flowing out of a vehicle engine E to a heating circuit, with the present rotating speed Rx of a driven pulley 53 or a rotor. That is, if the detected rotating speed Rx reaches the set cutoff rotating speed, the control device 71 cuts off power transmission from the vehicle engine to the heat generator 16 through the electromagnetic clutch 51. The prevention of degradation of a visous fluid and the improvement of buildup performance of heating capacity can be combined by setting the cutoff rotating speed variably according to the water temperature Tx.

摘要： PROBLEM TO BE SOLVED: To prevent the deterioration of viscous fluid due to excessive heating of the viscous fluid in the viscous heater. SOLUTION: Front and rear housing main bodies 1, 2 and front and rear partition plates 5, 6 constitute a heater housing, in which a heat generation chamber 7 which stores a rotor 14, two jackets (heat radiation chamber) 8, 9 arranged in the front and rear of the heat generation chamber 7, and an auxiliary oil chamber (storing chamber) 10 communicated with the heat generation chamber 7 are partitioned. A required amount of silicone oil (viscous fluid) is filled in the heat generation chamber 7 and the auxiliary oil chamber 10. A plurality of heat absorption fins 21, 22 are formed on front and rear inner walls of the auxiliary oil chamber 10. Excessive heat is rapidly absorbed from high temperature oil recovered from the heat generation chamber 7 into the auxiliary oil chamber 10, and heat is transferred to the rear partition plate 6 and the rear housing main body 2 to discharge the heat into the circulation water which flows in the rear water jacket 9.

摘要： PROBLEM TO BE SOLVED: To improve the durability of viscous fluid by improving the heat transmission property from a heat generation room to a heat radiation room. SOLUTION: In this viscous heater, the wall surface of a heat generation room, namely the recessed part 2c of a front side plate 2 and the front end surface of a rear side plate has plural recessed parts (long grooves 23a and short grooves 23b) extended in a radius direction) as a heat transmission improving means for improving the heat transmission property from the heat generation room to a heat radiation room. This recessed part is formed so that an outer periphery side becomes dense for the inner periphery side of the heat generation room. As the heat transmission area on a heat generation room wall surface is increased by the side area of the recessed part, the heat transmission amount from the heat generation room to the heat radiation room can be increased. Especially, as the outer periphery side is formed so as to be dense for the inner periphery side of the heat generation room, the heat transmission from the heat generation room to the heat radiation room can be carried out effectively at the outer periphery side easy to become higher temperature and also the deterioration of a viscous fluid by that the temperature of the viscous fluid is increased excessively in the heat generation room can be restrained.

摘要： PROBLEM TO BE SOLVED: To provide a method for causing circulation of circulating water at a high heat exchange efficiency in a viscous heater. SOLUTION: A water jacket 8 serving as a heat radiation chamber adjacent to a heating chamber via a partition plate 5 is provided in a housing 1. Two vertically aligned ports 10, 11 communicated to the water jacket 8 are formed in the housing 1. Guide walls 5a, 5c, 5d, 5e in the form of concentric circles are provided in the water jacket 8 to set a plurality of annular circulation passages P1, P2, P3 leading from one port to the other. Circulating water is introduced into the water jacket 8 from the lower port 10 and is guided out from the upper port 11 via the annular circulation passages P1, P2, P3. Thereby in each annular circulation passage the circulating water is circulated in one direction from its lowest level LP to its highest level HP to prevent air from staying in the water jacket 8.

摘要： PROBLEM TO BE SOLVED: To sufficiently restrain impact to occupants accompanying change of the operating condition by continuously smoothly controlling the operating condition of a heat generator such as start/stop and rotating speed, so as to restrain impact generating at controlling the heat generating quantity. SOLUTION: Heat generated at a viscous heater 10 is supplied to the cooling water of an engine 1, the heat together with heat absorbed from the engine 1 is radiated to a vehicle room through a heater core 11 so as to attain heating in the vehicle room. Control of the operating condition of the viscous heater 10 (conditions such as start/stop and rotating speed (heat generating quantity)) is performed by controlling the dynamic pressure and the oil quantity of working oil through valve devices 56 (a changeover valve 6 and a control valve 5), and hence the operating condition is continuously smoothly changed. Consequently, compared with a device intermittently controlling by an electromagnetic clutch, impact applied to occupants accompanying change of the operating condition can be sufficiently restrained, and hence the occupants can be prevented from feeling uncomfortableness.

摘要： PROBLEM TO BE SOLVED: To surely supply lubricating oil supplied to the inner wall of a front housing to a lip seal side. SOLUTION: An inner wall of a front housing 111 on which lubricating oil blown out of an injector passage 220 is collided is formed to be a slope surface 113 inclined downward more toward a bearing 150 side. Thus, lubricating oil supplied to the upper end side 113a of the slope surface 113 flows to the lower end side 113b of the slope surface 113 without falling through the slope surface 113 to a balancer 132 by its surface tension. Thus, since the lubricating oil is supplied to a lip seal 160 side (bearing 150 side) surely, the wear of the lip seal 160 is suppressed.

摘要： PROBLEM TO BE SOLVED: To downsize and reduce manufacturing cost of a whole device including equipment driven by hydraulic pressure, such as an actuator. SOLUTION: A pump mechanism 110 and a valve mechanism 120 are housed in a housing 104 for integrating the mechanisms 110, 120 with each other. The mechanisms 110, 120 are driven by one plunger 103. The valve mechanism 120 is opened and closed by switching ON and OFF current carrying through the coil 101. The pump mechanism 110 is driven by fluctuating application voltage to the coil 101. It is thus possible to downsize, that is, to reduce weight of whole of a viscous heater device and to thereby reduce manufacturing cost.

摘要： PROBLEM TO BE SOLVED: To provide a viscous heater capable of controlling calorific value with ease while improving carrying properties on a vehicle. SOLUTION: A second movable member 115 forming the inner wall of a heat generation chamber 102 located at a position outside a heater shaft 104 in its radial direction is made to displace in the radial direction of the heater shaft 104, and air is also made to enter the heat generation chamber 102 together with viscous liquid. Through such operation, when the volume of the heat generation chamber 102 is expanded, since the air is expanded in the heat generation chamber 102, the rotation of a rotor 103 does not generate heat. On the other hand, when the volume is shrunk, the air gathers in an air chamber 403, and the heat generation chamber 102 is filled with viscous fluid, resulting in heat generation.

摘要： PROBLEM TO BE SOLVED: To reduce the manufacturing cost of a scroll compressor while preventing the cracking and breakage of a joint portion (the root of a spiral wall) on the spiral center side and decreasing efficiency of the compressor. SOLUTION: The radius (r) of curvature of a joint portion 12a between a spiral wall 12 and a base 11 is made constant over the whole periphery in the spiral direction and an angular portion 12b of the spiral wall 12, corresponding to the, joint portion 12a, is formed in an approximately circular shape. Therefore, no recombination of an end mill is required over the whole periphery in the spiral direction and machining work is done by one end mill, resulting in a less number of manufacturing processes. As a rounded portion 12c is formed on the angular portion 12b, a gap δ formed between the angular portion 12b and the joint 12a can be smaller. The manufacturing cost can be reduced, accordingly, while preventing the cracking and breakage of the joint 12a on the spiral center side and the decreasing efficiency.

摘要： PROBLEM TO BE SOLVED: To provide an auxiliary heating apparatus for a vehicle capable of maintaining temperature of a viscous fluid inside and outside uniform by roughly making a calorific value of the viscous fluid constant on the inside where shearing speed of the viscous fluid is low and on the outside where the shearing speed of the viscous fluid is high. SOLUTION: A gas heater (auxiliary heating apparatus for vehicle) 1 is constituted by narrowing a plate interval toward the inside than a normal value and widening the plater interval toward the outside than the normal value without making the plate interval between a rotating plate 9 provided in a heating chamber 10 free to rotate and first and second fixed plates 5, 6 arranged facing against each other on both end surfaces of this rotating plate 9 constant inside and outside. Consequently, it is possible to make a calorific value from the inside to the outside of the heating chamber 10 near to average calorific value by making a calorific value of a viscous fluid from the inside to the outside of the heating chamber 10 roughly constant. Accordingly, it is possible to eliminate temperature distribution of the viscous fluid in the heating chamber 10 and to lower the maximum temperature of the viscous fluid while working.
摘要翻译：要解决的问题：提供一种用于车辆的辅助加热装置，其能够通过使粘性流体的剪切速度低的内部的粘性流体的热值恒定地保持均匀，从而保持内部和外部粘性流体的温度; 在粘性流体的剪切速度高的外侧。解决方案：一种气体加热器（车辆用辅助加热装置）1是通过使板间隔向内部变窄而不是正常值而构成，并且在不使正常值的旋转板9之间的板间隔不使板间隔延长的情况下，在自由旋转的加热室10中，在该旋转板9的两端表面上彼此相对配置的第一和第二固定板5,6在内部和外部保持恒定。因此，通过使加热室10的内部至外部的粘性流体的热值大致恒定，可以使加热室10的内部至外部的热值接近平均热值。因此，可以消除加热室10中的粘性流体的温度分布，并且在加工时降低粘性流体的最高温度。
