摘要： A scroll type fluid machine having two scroll members each having an end plate and a spiral wrap formed on the end plate, the scroll members being coupled to each other such that the wraps thereof mate with each other. One of two scroll members being adapted to make an orbitary movement with respect to the other scroll member while being prevented from rotating around its own axis, so as to form at least one working chamber of different pressures between two scroll members. At least two pressing force imparting chambers are formed on the opposite side of the orbitary scroll member to the wrap. The pressing force imparting chambers includes a first chamber which is communicated through a communication passage with at least one of the working chambers which is not materially communicating with a low pressure port and is not at all communicating with a high pressure port of the machine, and a second chamber which is communicated with the high pressure port through a communication passage, so that fluid pressures of different levels are applied to the first and second pressing force imparting chambers so as to produce a force which presses the orbitary scroll member to the other scroll member.

摘要： In a scroll-type compressor, the sum of pressure receiving areas of the upper end surfaces of crank portion of a crankshaft and the upper end surface of a balance weight is made substantially equal to the sum of the pressure receiving areas of the lower end surface of the shaft portion of the crankshaft and the lower end surface of the balance weight, the surfaces being subjected to internal pressures of the compressor. Consequently, only the downward force produced by the weights of the crankshaft and the rotor of a driving motor is applied to the crankshaft as an axial load which is born by a thrust bearing. Since the thrust bearing is required only to bear a small thrust load, it is free from the problems such as rapid wear and seizure.

摘要： The scroll type compressor has a hermetic casing, and a scroll compressor section and an electric motor section which are contained within the hermetic casing. 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 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.

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 sealed scroll compressor comprises a scroll compressor section, an electric motor, a sealed container, an oil storage, a fixed and orbiting scroll members, and a wire mesh member for improvement of oil separation in refrigerant gas. A shell portion of said sealed container is lined annularly with the wire mesh member and the gas containing oil is adapted to flow downwardly along the wire mesh member. When the gas flows downwardly, the oil sticks to the wire mesh member and is separated from the gas. The oil collected on the wire mesh member drops down into the oil storage. The gas from which the oil is separated is, after that, discharged out of the compressor.

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.
