    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： 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..
