摘要： An oil feeding device for a scroll fluid apparatus. A fixed scroll member is associated with an orbiting scroll member. A crankshaft rotatably supported by a bearing of a frame has a crank portion engaging with a plain bearing of the orbiting scroll member. A variable speed driving motor is connected to the crankshaft. An oil feeding passageway is provided in the crankshaft and the crank portion. Oil is supplied to the plain bearing of the orbiting scroll member through a space at the end face of the crank portion. An oil flow passage is provided in parallel with the axis and in a surface of the crank portion located at a position advanced through approximately 45 degrees toward the rotational direction of the crank portion, from a position at which the load acting radially of the shaft due to the centrifugal force caused by the orbiting motion of the orbiting scroll member is applied to the crank portion of the shaft.

摘要： A scroll-type fluid machine having an orbiting scroll member and a stationary scroll member each having an end plate and a spiral wrap of at least two turns protruding upright from one of the sides of the end plates. The orbiting scroll member has a back pressure chamber formed on the back side thereof and communicating with the compression spaces of the fluid machine through pressure equalizing ports formed in the orbiting scroll member, so that the pressure of the fluid under compression is introduced to the back pressure chamber to produce an axial thrusting force for pressing the orbiting scroll member towards the stationary scroll member. The positions of the pressure equalizing ports in terms of the wrap angle .lambda. of the wraps are selected to meet the following condition:.lambda.d>.lambda.>.lambda.d-2.pi.,where, .lambda.d represents the wrap angle of the wraps when the volume of the compression spaces is minimized. The equalizing ports are positioned at .lambda. and .lambda.+2 .pi..

摘要： A refrigerating system including a refrigeration circuit and a scroll type compressor provided with two volume control mechanisms to allow the system to selectively perform full load operation and unloaded operation. The scroll type compressor includes two scroll members of known construction meshing with each other to define compression chambers and a suction chamber and is combined with the refrigeration circuit having an outdoor heat exchanger, an expansion valve, an indoor heat exchanger and a four-way change-over valve to provide a heat pump type refrigerating system. The volume control mechanisms each include a pair of bypass apertures in the fixed scroll member communicating with a valve chamber having a valve member slidably mounted therein and normally biased to an open position by a spring. The bypass apertures, of which one communicates with the suction chamber and the other communicates with one of the compression chambers, and the valve chamber constitute a bypass passageway. A pressure introducing pipe opens in the valve chamber. Upward movement of the valve member brings the two bypass apertures in communication with each other through the valve chamber to enable the system to perform a volume control operation. In another application, four volume control mechanisms are located symmetrically and divided into two blocks through a flow passage switching device to assign two mechanisms to one block. By this arrangement, the system is able to perform volume control operation in three stages, or able to operate selectively at maximum load, intermediate load and minimum load.

摘要： A scroll-type fluid machine comprises a stationary scroll member, an orbiting scroll member, a rotation-prevention mechanism for the orbiting scroll member, and a casting accommodating therein both members and the mechanism. The involute angle of a terminal end of a wrap of the orbiting scroll member is selected to be less than that of the wrap of the stationary scroll member by an angle which ranges between 60.degree. and 120.degree., preferably, about 90.degree., thereby reducing a level of force applied to the rotation-prevention mechanism which prevents the orbiting scroll member from rotating about its own axis.

摘要： A scroll-type fluid machine having a stationary scroll member and an orbiting scroll member each of which includes a disc-like end plate and a spiral wrap extending axially from one side of the end plate, with the wraps of the scroll members meshing with each other to define therebetween closed compression chambers. The orbiting scroll member is disposed between the end plate of the stationary scroll member and a frame of the machine with a back clearance between the other side of the end plate of the orbiting scroll member side thereof and the opposing surface of the frame. The orbiting scroll member is driven to make an orbiting movement with respect to the stationary scroll member so that the compression chambers are progressively moved towards the center of the scroll members while decreasing their volumes, to thereby suck a fluid through a suction port in the stationary scroll member and compress the same to discharge the compressed fluid through a discharge port formed in the stationary scroll member. The radial clearance between the wraps of both scroll members is selected to meet a specific condition so as to avoid mutual contact between the wraps of the scroll members even when the orbiting scroll member is inclined with respect to the horizontal plane.

摘要： A hermetic motor-compressor for a refrigerating system. The hermetic motor-compressor has a motor component and a compressor component drivingly coupled to each other and disposed within a closed container. The refrigerant gas introduced from an evaporator of a refrigerating system through a return pipe is once released into the space within the closed container and then sucked by the compressor component so as to be compressed and discharged to the outside. A barrier is provided on the outer periphery of the motor and compressor components for preventing a main flow of the refrigerant gas introduced into the closed container through the return pipe from flowing into the circumference of high-temperature portions of the hermetic motor-compressor.
