摘要： A compressor of the swash plate type for a refrigerating machine in which an oil separating chamber is formed in one portion of each of a plurality of cylinder block elements, and two sets of balance holes are formed therein, one set disposed between the oil separating chambers and a crank-case and the other set disposed between the oil separating chambers and a low pressure gas passage. By this arrangement, blow-by gas is ejected at high speed from the crank-case into the oil separating chambers, impinges on walls of the oil separating chambers, and changes its directions of movements to flow into the low pressure gas passage. During this process, lubricant is separated from the blow-by gas and recovered for further use.

摘要： A vane-type rotary machine suitable for use as a compressor, pump or the like, having a cylinder provided with an inner peripheral contour expressed by an epitrochoid-like curve having at least one lobe, a cylindrical rotor contacting the inner peripheral surface of the cylinder and having a plurality of vane grooves, and vanes slidably received by respective vane grooves. The inner peripheral contour of the cylinder constituted by the epitrochoid-like curve is divided at the circumferential mid point of each of the portions where the distance between the rotor and the cylinder is minimized, and the curve is contracted in the circumferential direction by a predetermined angle to form a discontinuity corresponding to the predetermined angle. Both end points of the discontinuity is connected by an arc of the same radius as the rotor.

摘要： A vane-type rotary machine for use as a compressor, pump or the like. The rotary machine has a cam ring with an inner peripheral contour expressed by an epitrochoid-like curve having at least one lobe, a cylindrical rotor having a plurality of vane grooves and contacting the inner peripheral surface of the cam ring, and vanes slidably received by the vane grooves and adapted to slide on the inner peripheral surface of the cam ring as the rotor rotates. The inner peripheral contour of the cam ring is corrected or modified in accordance with the amount of offset of the vanes in such a manner as to suppress the lateral reactional force applied to the vanes thereby to reduce the friction loss during sliding of the vanes in respective vane grooves, while making the sliding movement of the vanes approach a movement in accordance with a sine wave curve, thereby to diminish noise, thermal loss and mechanical damage which are attributable to irregularity of movement of the vanes.

摘要： An oil separator for separating oil from exhausted gas containing refrigerant gas and fine particles of oil incorporated in the refrigerant gas including grooved plates each formed with a multiplicity of grooves on opposite surfaces to allow the exhausted gas to flow in a direction substantially at right angles to the grooves, whereby the fine particles of oil can be trapped by the grooved plates. The oil separator can achieve increased oil separation efficiency.

摘要： PURPOSE:To prevent gall and abnormal abrasion of a ball joint during operation with a less volume of coolant, by forming a solid lubricating film having a wear resistant function on the spherical part and/or the inner surface of the ball join of a connecting rod. CONSTITUTION:An anodic oxide coated film 9c as a base is formed on the inner surface 9b of a ball joint which holds therein a spherical part 8a of a connecting rod, and the film 9c is coated with powder obtained by mixing resin with a binder and having MOS2 as a main component so as to form a solid lubrication film 9. Further, a part of the inner surface of the ball joint is formed therein with a space for holding therein lubrication oil.

摘要： PURPOSE:To keep a constant revolution speed of a compressor by shifting a centrifugal weight to the outside in the radial direction of a V-pulley by the increase of the revolution speed of the V-pulley and reducing the pitch radius of the V-pulley on an engine side. CONSTITUTION:A transfer plate 17 is pressed onto a fixed plate 16 by a coil spring 19. When the engine revolution speed increases, a pulley consisting of a fixed plate 5 and a transfer plate 8 on a compressor side shifts from the position shown by the full line to the position shown by two-point chained line against the pressing force of the coil spring 19 by the centrifugal force of a centrifugal weight 7. A movable plate 8 and a V-belt 9 are shifted to the small diameter bottom side at the position shown by each two-point chained line. Therefore, as the engine revolution speed increases, the speed ratio between a compressor and the engine varies from the speed increase to the speed reduction continuously for the engine, and the compressor can be operated always at a constant revolution speed.
