摘要： PURPOSE: To reduce both of bearing load and end tooth bearing as well as to aim at preventing the occurrence of wear and seizure or binding, by supporting a shaft part with a rolling bearing installed in position nearby a crank part and a sliding bearing installed in position away from the crank part in a frame.
CONSTITUTION: A rolling bearing 36 is installed in a radial part comprising a crank part 9b and a turning scroll 3, while a thrust type rolling bearing 37 is set up in position between the turning scroll 3 and an upper part of the crank part 9b. Lubrication to these bearings takes place via an eccentric lubricating passage 19 and a choke 38 installed in the upper end of this passage 19. Therefore, an oil chamber 20 on top of the crank part 9b comes into a state of being intermediate pressure whereby a crankshaft 9 is to receive the thrust load produced by a difference between discharge pressure and this intermediate pressure at its upper part but this thrust load can be absorbed by the thrust type rolling bearing 37. In addition, the amount of oil discharged out of the rolling bearing 36 is regulated by the choke 38 so that a constant drain oil quantity can be secured all the time. With this constitution, bearing load and end tooth bearing both are reduced, thus an effective prevention against wear and tear to these bearings and end plates or the like comes to fruition.

摘要翻译：目的：为了减少轴承负荷和端齿轴承，同时为了防止磨损和卡扣或装订的发生，通过支撑安装在曲轴部件附近位置的滚动轴承的轴部件和安装在其中的滑动轴承在框架中远离曲柄部分的位置。构成：滚动轴承36安装在包括曲柄部分9b和转动涡卷3的径向部分中，而推力型滚动轴承37设置在转动涡旋件3和曲柄部分9b的上部之间的适当位置。这些轴承的润滑通过设置在该通道19的上端的偏心润滑通路19和扼流圈38进行。因此，曲柄部9b顶部的油室20成为中间压力的状态， 9接收由上部排出压力与该中间压力之差产生的推力载荷，但该推力载荷可由推力式滚动轴承37吸收。此外，从滚动轴承排出的油量 36由扼流圈38调节，从而可以始终确保恒定的排出油量。利用这种构造，轴承负载和端部轴承两者都减小，从而有效防止这些轴承和端板等的磨损和破坏。

摘要： PURPOSE:To reduce the size of a balance weight, the dimensions of a bearing and the size and weight of a compressor, by a method wherein the crank part of a crankshaft is hollowed so as to reduce the quantity of rotational unbalance of the crankshaft. CONSTITUTION:The crank part 9 positioned at the upper end of a crankshaft 4 is provided with an eccentric hollow part 9a, which is so located as to reduce the quantity of rotational unbalance of the crank part 9. In this way, the quantity of rotational unbalance of a scroll compressor is reduced, and the balance weights 23, 24 (not shown) for eliminating the rotational unbalance can be made to be small in size, enabling to reduce the fitting space, that is, the dimension between the crank part 9 and a main bearing (not shown). Accordingly, the compressor can be made to be small in size by the combined effect of the reduction of the size of the balance weight and the reduction of the dimention between the crank part 9 and the bearing.

摘要： PURPOSE:To prevent an increase of the suction gas speed and to reduce the suction resistance of the suction gas by forming a gas suction chamber around the outside of a lap made by coupling a rotary scroll and stationary scroll with each other. CONSTITUTION:A gas passage 20 is formed on the outside of a lap made by coupling a stationary scroll 19 and rotary scroll 5 with each other so as to be connected to a suction chamber 12 and to form a gas suction chamber around the outside of the lap. The gas passage 20 is provided so as to form a groove on the bed plate side of the stationary scroll 19 from points (a), (b) corresponding to an external line A of the winding end of the rotary scroll 5 around the lap of the stationary scroll 19 and an external line B of a winding angle forming the maximum sealed space. Thereby, the suction gas is sucked even under a condition that the gap between the external line A of the rotary scroll 5 and the corresponding point (a) on the path of the suction chamber 12 of the stationary scroll 19 is small when the compression stroke is completed.

摘要： PURPOSE:To enable to flow condensate water smoothly in a heat exchanger without affecting the heat transmitting performance, by employing such an arrangement that corrugated fins to be stretched perpendicularly to the length of a flat heat transfer tube are arranged with some inclination angle, instead of arranging the same horizontally. CONSTITUTION:A flat heat transfer tube 11 is bent continuously in a zigzagged manner, so that a plurality of straight tube sections 11a, 11b-11n are formed in parallel with each other to extend vertically with uniform intervals. Corrugated fins 12 are extended between adjacent two straight tube sections and their turning points 12' are welded thereto. Here, arrangement is such that fin plates 112a, 112b before forming corrugation thereto are not rectangular but are shaped in the form of an inclined parallelogram. Resultantly, corrugated fins 12 are welded to the straight tube sections 11a, 11b-11n at their bent point or joining points 12' on the opposit sides of the corrugated fins 12 at an angle theta to the length L of the straight tube sections, in the manner that air flow A descends toward the downstream side. Similarly, unit fin surfaces 12a are also arranged to have downward inclination.

摘要： PURPOSE: To prevent lowering of the volumetric efficiency of a scroll compressor due to leakage of gas, by fitting an annular seal member between sliding surfaces of a fixed and a turning scrolls having respectively a volute lap erected on its flat plate part, and improving the sealing performance at slidable parts by applying back pressure at the back surface of the annular seal member.
CONSTITUTION: When a crank shaft 4 is set into rotation along with rotation of a rotor 3a, a turning scroll 6 is turned by an eccentric shaft 4a and a turning mechanism 14. This causes change in the volume of a space defined between the turning scroll 6 and a fixed scroll 7, so that gas introduced from an inlet pipe 19 is compressed and discharged to an outlet pipe 10. Here, since pressure n an intermediate pressure chamber 16 is kept equal to that in a compression chamber 18 by the function of a connecting port 17, the above two scrolls 6, 7 are brought into sliding contact with each other. In the above arrangement, an annular groove 21 is formed at the sliding parts of one scroll 7 and a seal member 22 is fitted therein. Further, the groove 21 is communicated via an oil port 23 to an oil sump 24 at the bottom of an enclosed casing 1. Therefore, it is enabled to positively seal the sliding parts of the two scrolls 6, 7.

摘要： PURPOSE:To increase a rigidity of a compressor by a method wherein a number of cylinders are properly arranged to make a small-sized compressor and a length of the crank pin is made to be sufficient with a length of one connecting rod. CONSTITUTION:In the drawing is illustrated a case in which a piece of crank pin 20 is applied, three of the cylinders are radially arranged in the same plane which is crossed at a right angle with a crank shaft, two of the arranged planes are set in parallel in their axial direction. That is, the cylinders are arranged such that the cylinders 27a, 27b, 27c in other arranging planes are positioned at intermediate portion of the cylinders 26a, 26b, 26c in the same arranging plane. In this way, a number or cylinders are properly arranged to make a small-sized compressor. Even if a plurality of cylinders are radially arranged in the same plane, the crank pin 20 may sufficiently be applied in a length of one connecting rod, thus a rigidity of the crank pin 20 may also be increased.
