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 scroll-type fluid machine is provided with a plurality of liquid-confining pockets formed in the sliding surface of the end member of either one of orbiting and stationary scrolls. In operation, a high liquid pressure is generated in the pocket or pockets positioned in the region where a localized high axial urging force is exerted during operation, so that the localized high axial urging force acting on the two scrolls is partially or fully negated.

摘要： A scroll fluid machine comprises compression chambers defined with an orbiting scroll orbiting relative to a fixed scroll, and a back pressure chamber provided on the face opposite from a wrap of the orbiting scroll. A back pressure port is provided, which is formed in an end-plate of the orbiting scroll and connects from a compression chamber side opening opened to a compression chamber side and to a back pressure chamber side opening opened to a back pressure chamber side. The compression chamber side opening is opened and closed by an end-plate of the fixed scroll according as the orbiting motion of the orbiting scroll to perform connection and blockage of the back pressure port. The flow resistance of fluid flowing in and out between the back pressure chamber and the compression chamber is reduced and the compression efficiency and reliability are improved.

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： 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.
