    摘要: A scroll compressor comprises two scroll members, each of which has an end plate and a wrap formed on the end plate so as to extend perpendicularly therefrom, are meshed with each other, one scroll member being orbited with respect to the other without being self-revolved, to introduce a gas into working chamber. The working chamber is formed by these two scroll members, compresses the gas therein and then discharge the same to the outside. A seal mechanism for pressure-sealing between the working chamber or the suction side and a space on a rear surface of the orbiting scroll member is provided on the same rear surface, and also a pair of small-diameter ports for communicating the mentioned space and working chamber with each other are provided on the end plate of the above-mentioned scroll member, whereby the outer diameter of the scroll members can be minimized, and the axial opposed end surfaces of the two scroll members can be maintained in sealed condition.

    摘要: A synchronous rotating type scroll fluid machine has a first scroll member driven by a shaft of a first motor and having an end plate and a scroll wrap protruding from a surface of the scroll end plate, and a second scroll member driven by a shaft of a second motor and having a scroll end plate and a scroll wrap protruding from a surface of the scroll end plate. The machine further has a mounting structure for mounting the scroll members such that the axes of the scroll members are offset from each other and that said scroll wraps of the scroll members mesh with each other. Thrust balancing arrangements are provided for attaining a balance between the thrusting forces acting on each said scroll member, both at the mounting structure and said scroll members. The thrust balancing arrangement includes through-bores formed in the respective motor shafts and serving as passage bores for discharging a compressed gas. This arrangement also provides cooling effect as the compressed working gas functions as a cooling medium and, in addition, serves to suppress distortion of the scroll end plate of each scroll member.

    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: The variable capacity swash plate compressor of the present invention includes a rotary swash plate having an eccentric mass located opposite to the driving point of the swash plate with respect to the axis of the same. The mass distribution in the rotary swash plate is established such that, within a range in which the piston stroke is less than a predetermined value, a moment about a pivot point produced by the rotation of the swash plate becomes larger than a moment produced by the reciprocating motion of pistons, piston rods and the like and acting upon the swash plate, while, within a range in which the stroke is larger than the predetermined value, the former moment becomes smaller than the latter moment. Accordingly, it is possible to provide a compressor of the type in which its capacity control characteristics are improved over a wide shaft speed range.

    摘要: A refrigeration system includes a variable-capacity compressor having a compression chamber for sucking and compressing a refrigerant and a crankcase surrounding a swash plate forming a drive portion for suction and compression, and a passage through which the refrigerant discharged from the outlet of the compression chamber passes at least through a condenser, an expansion means and an evaporator and is sucked into the inlet of the compression chamber of the compressor, the capacity of the compressor being changed by slanting the swash plate during its rotation. A pressure control device is provided in a refrigerant passage between the evaporator and the suction valve of the compressor whereby the pressure upstream thereof is controlled in such a manner that it does not decrease below a predetermined value, thereby preventing frosting of evaporator fins. A point partway along the passage upstream from the pressure control device and the crankcase of the variable-capacity compressor are communicated so that the capacity of the compressor may be controlled without controlling the pressure in the crankcase.
