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 provide an auxiliary heat source device integrally incorporated with a generator, in which a viscous heater can be simply held on an alternator even though the shaft of the alternator, the shaft of the viscous heat and a pulley are integrally incorporated with each other in the heat source device. SOLUTION: A viscous heater 7 is laid on the pulley 16 side remote from to a position where electric parts such as a rectifying device 2 attached to an alternator 6, a voltage regulator 27, a current collector 28 and a brush device 9 are arranged, and remote from a position where a lightweight but low rigid protecting cover 30 is attached, and accordingly, the heater 7 can be assembled to a housing 23 having a high rigidity and attached to an engine. Thus, it is not required to cause the protecting cover to have a high rigidity and a heavy weight, thereby it is possible toprevent the total weight of the auxiliary heat source device integrally incorporated with a generator, from increasing.

摘要： PROBLEM TO BE SOLVED: To restrain the generation of such heat loss that a heat generated in a heat generating room is released to the atmosphere through a housing and increase the heat exchange rate to a heat radiating room, in a vehicular heat generator. SOLUTION: A heat generating room 7 and front/rear partition plates 5, 6 for partitioning both water jackets 8, 9 are stored in front/rear housing main bodies 1, 2. In both partition plates 5, 6, as their outer periphery walls are contacted with the inner periphery wall of the front housing main body 1, periphery grooves 5d, 6d as a recessed part extending to a periphery direction are provided recessingly on the outer periphery wall, while being positioned so as not to be moved. Such periphery grooves 5d, 6d form one part of the circulation passage of a circulation water in both water jackets 8, 9 and the inner walls of the periphery grooves 5d, 6d guide the flow of the circulation water. Meantime, the circulation water absorbs a heat generated in the heat generation room 7 and also the heat transmission to the front housing main body 1 is stopped at the minimum.

摘要： PROBLEM TO BE SOLVED: To realize a quick heating in starting in a heat generator using a viscous fluid heated by the shearing action by the rotation of a rotor as the heating source of a cabin by providing a moving means for moving the viscous fluid to a liquid-tight clearance side between the liquid-tight clearance and a storing area. SOLUTION: When a drive shaft 8 is driven by an engine, a rotor 9 is rotated within the heating chamber 5 of a viscous heater VH, and silicone oil SO is heated in a cylindrical and disc-like liquid-tight clearance between a housing 1 and the rotor 9 by receiving a shearing force. Since the temperature of the cooling water within a water jacket WJ is raised by heat exchange by this heating, the heated cooling water is utilized for heating of a cabin and warming of the engine through a heating circuit. In this case, the silicone oil SO which is apt to be unevenly present on the inside surface of the cylinder part 11 of the rotor 9 is centrifugally guided to the guide part of a protruding part 23, passed through a connecting clearance 22 and moved to a supplying groove 24, so that the heating efficiency can be improved.

摘要： PROBLEM TO BE SOLVED: To smoothen the start of a rotor by quickly reducing the load torque when the rotor is to be started. SOLUTION: A collection passage 20 to put a heat generating chamber 7 in communication with a storage chamber is formed in the body of a front housing and two partitioning plates 5 and 6. The passage 20 is arranged so that its center Y in the communicating direction is identical to a virtual center surface CP which divides a rotor 14 into two in its axial direction. Accordingly the opening of passage 20 on the side with heat generating chamber 7 has a uniform section area for the front L1 and rear clearances L2 of the rotor 14 in the chamber 7. The passage 20 extends from the mentioned opening to another opening on the side with the storage chamber in such a way as in line with a leadout groove 23.

摘要： PROBLEM TO BE SOLVED: To reduce starting torque and feed a viscous fluid rapidly to a heating chamber after starting by making the level of the viscous fluid in a storage chamber changeable regardless of the opened/closed state of a recovery passage and a feed passage. SOLUTION: A diaphragm 30 is provided to partition a storage chamber SR into a storage area on the side of a feed hole 2c and a recovery hole 2d, and a non-storage area on the side of an atmosphere hole 2e, and the diaphragm 30 is fixed to a laterally slidable spool 31. At the time of an engine stop, an electromagnetic coil 34 is excited. Then, the spool 31 enlarges the volume of the storage area against the energizing force of a press spring 32, and silicone oil SO in the storage area is fed only in small quantity to a heating chamber 6 with own small weight based on the low level (h) so as to reduce starting torque. After starting, the electromagnetic coil 34 is demagnetized. The volume of the storage area is therefore reduced, and the level of the silicone oil SO rises and is fed in large quantity to the heating chamber 6 on the basis of the high level so as to attain rapid heating.

摘要： PROBLEM TO BE SOLVED: To ensure the calorific value of a viscous heater per one rotation of its rotor as well as prevent the wear of the outer periphery of its rotor and the inner wall of its heating chamber. SOLUTION: A front housing 1, a section plate 2 and a rear housing body 3 are united with a bolt 5 through a gasket 4, and a heating chamber 7 and a water jacket 8 are defined in the united housing. A rotor 13 arranged in the heating chamber 7 is forcibly fitted on the rear end of a driving shaft 12 so as to freely rotate therewith. The heating chamber 7 is charged with silicone oil to produce heat through the shear thereof caused by the rotation of the rotor 13. The heating chamber 7 is enclosed by a pair of walls situated in its front and rear and by the cylindrical peripheral wall, and the front and the rear end faces and the outer periphery of the rotor 13 face the walls and the peripheral wall. The rotor 13 is bulged outward at the center of its both front and rear ends.

摘要： PURPOSE: To provide a single head piston type compressor which can prevent washdown of lubricating oil caused by liquid refrigerant even at the starting and which can keep a crank room in a good lubricated condition. CONSTITUTION: An oil pan 37 is formed in a projected manner, ranging over the outer side surfaces of a cylinder block 11 and a front housing. The oil pan 37 is communicated with a crank room 22 by a communicating hole 38 at the rear and upper part of the pan 37. A first oil feeding passage 39 is prepared between the oil pan 37 and a front-side bearing part of a driving shaft 16. One end of the first oil feeding passage 39 is opened above the highest liquid level (L) of the liquid refrigerant 45 in the oil pan 37, while the other end is opened in the vicinity of the point above the lowest end of the driving shaft 16. The driving shaft 16 is provided with a second oil feeding passage 40 in such a manner that the second passage 40 is almost communicated with the first passage 39, and the passage 40 is opened at a swash plate and at the neighborhood of a rear-side bearing part.
