摘要： A scroll compressor is provided with a two groups of commmunication ports formed in and extending through an end plate of a stationary scroll member. Each group includes two or more communication ports. A lead valve is associated with each of the two groups of communication ports and is operable by a pressure differential in between an associated compression chamber and the discharge chamber to communicate the communication ports of the group to the discharge chamber to prevent the occurrence of over-compression in the compression chamber.

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 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： An air conditioner includes a scroll-type refrigerant compressor driven at a speed variable in accordance with the thermal load on the air conditioner. The compressor has stationary and orbiting scroll members assembled together to define compression chambers in which a refrigerant gas is compressed and finally discharged into a discharger chamber through a discharge port formed in the center of the end plate of the stationary scroll member. At least one bypass port and an associated check valve are provided in and on the end plate of the stationary scroll member at such a position that the check valve opens to allow the gas to be directly discharged from an associated compression chamber into the discharge chamber when the compressor is operated under such a condition that the ratio of the operation pressure ratio to the design pressure ratio of the compressor falls within a range between 0.5 and 0.75.

摘要： A scroll compressor including a stationary scroll and an orbiting scroll, with an intermediate pressure chamber being defined on a back side of the orbiting scroll member and being in communication with a pressure chamber through a communication hole to produce a force for pressing the orbiting scroll against the stationary scroll. Oil in an oil sink is supplied to sliding portions by a differential pressure between a pressure in the air tight container and a pressure in the intermediate pressure chamber. A valve is provided for switching the connection of the intermediate pressure chamber to a higher intermediate pressure side or to a lower intermediate pressure side of the compressor. The valve is constructed such that the intermediate pressure chamber is connected to the lower intermediate pressure side of the compressor when a discharge pressure of the compressor is lower than a certain value and connected to the higher intermediate pressure side of the compressor when the discharge pressure is higher than a certain value so that a proper oil supply pressure is maintained over a wide operational range.

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： 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 hermetic motor compressor for compressing refrigerant gas in air conditioners or refrigerators. The hermetic motor compressor includes a motor compressor disposed in a closed housing and consisting of a motor section and a compressor section formed integrally with each other. The compressor section has a cylinder head cover, discharge silencer and discharge tube through which the compressed refrigerant gas is discharged to the outside. The cylinder head cover, discharge silencer and discharge tube are covered by heat insulating members with suitable spaces provided therearound. Heat radiation from the discharge system is therefore prevented by the spaces as well as by the heat insulating members, so that the temperature rise of refrigerant gas in the closed housing is avoided to ensure a higher volumetric efficiency of the compressor.
