摘要： A scroll compressor comprises an orbiting scroll and a fixed scroll, each of which includes a spiral wrap. These orbiting and fixed scrolls define between their wraps a plurality of close spaces at symmetrical positions. These closed spaces are moved toward the center of the scrolls by means of orbital motion of the orbiting scroll relative to the fixed scroll for reducing their capacities to compress fluid confined therein. Upon starting the compressor, some of the spaces which are in mid course of compressing and the other closed spaces which locate at the downstream side just before the communication with a discharge port, are communicated with each other through valves which open when pressure in the closed spaces at the upstream side is higher than that in the closed spaces at the downstream side, whereby a loading torque upon starting is decreased.

These compressor and electric motor sections are fitted through a frame in the hermetic casing. In a portion of the frame intermediate between the compressor and the electric motor section, a plurality of segmented concave spaces are defined. At an upper portion in the hermetic casing, a discharge space which communicates with a discharge port of the scroll compressor section is defined. Further, in a portion of the casing between the compressor and the motor section, a delivery port which open to one of the concave spaces in the frame is provided. Furthermore, at least one fluid passage is provided in an outer periphery of the compressor section and this passage makes the discharge space communicate with the other concave spaces in the frame. A compressed gas from the scroll compressor section is introduced via the discharge space and the fluid passage into the concave spaces, and is introduced from the delivery port to the outside of the compressor after separating the oil contained within the compressed gas in these concave spaces.

摘要： A scroll-type fluid machine includes an orbiting scroll member and a stationary scroll member each of which has an end plate and a spiral wrap protruding upright therefrom. The scroll members are assembled together such that their wraps mesh with each other. Closed spaces are defined by the wraps and end plates of both scroll members, and are progressively moved towards the center of the scroll members while decreasing their volumes in accordance with an orbiting movement of the orbiting scroll member. The edges of the projecting end of the wrap of each scroll member are chamfered. Also, steps are formed in conformity with the configuration of each spiral wrap on respective corners of the groove bottom between adjacent turns of the wrap. The chamfered edges of the projecting end of the wrap of each scroll member faces the steps on the groove bottom of the opposing scroll member, respectively, when the scroll members are assembled together.

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 scroll compressor comprises an orbiting scroll and a fixed scroll, each of which has a wrap formed on an end plate in upstanding position. These orbiting and fixed scrolls are assembled together with the wraps facing inwardly to each other so as to define a plurality of spaces by the wraps and the end plates of both scrolls. These spaces move toward the center of both scrolls during the orbiting movement of the orbiting scroll so as to reduce the respective capacities of the spaces. Thus, compression of a fluid is carried out. This compressor also includes a motor for driving the orbiting scroll and a driving shaft for connecting the orbiting scroll and the motor. At the end of the driving shaft on the motor side, a first oil supply pump is provided with its suction port communicating to an oil sump of the compressor. Also, a second oil supply pump communicating with the discharge side of the second oil supply pump is provided at the end of the driving shaft on the compressor section side, whereby the oil supply pump of the compressor is made of a multistage type.

摘要： Disclosed is a scroll-type fluid machine which has an orbiting scroll member and a stationary scroll member each having an end plate and a spiral wrap protruding upright therefrom. The scroll members are assembled together such that their wraps mesh with each other to form therebetween closed chambers of volumes which are progressively decreased as the chambers are moved toward the centers of the scroll members as a result of an orbital movement of the orbiting scroll member with respect to the stationary scroll member. The machine is suitable for use as a refrigerant compressor in a refrigeration system. A fluid check valve is disposed in the refrigerant gas suction passage connected to the suction side of the machine, so as to prevent any reversing of the orbiting scroll member. A passage is formed to provide a communication between a suction chamber defined by the scroll members and another closed chamber. A relief valve is disposed in this communication passage so as to relief any abnormal high pressure from the suction chamber.

摘要： A scroll-type compressor has an orbital scroll member and a stationary scroll member each having a disc-shaped end plate and a spiral wrap protruding upright from the end plate. The scroll members are assembled together with their wraps meshing with each other to define compression chambers therebetween. The orbital scroll member executes an orbital movement without rotating around its own axis. A discharge port and a suction port are formed in a central portion and a peripheral portion of the end plate of the stationary scroll member, respectively. As the orbital scroll member makes the orbital movement, the compression chambers are moved towards the center while decreasing their volumes thereby to progressively compress a gas drawn through the suction port and to discharge the compressed gas through the discharge port. The compressor further has a check valve disposed in a gas passage which is formed through the thickness of the end plate of the stationary scroll member so as to communicate with a suction chamber formed between the scroll members.
