摘要： This invention provides a piston in which the moving piston unit can be prevented from rotating with respect the base piston unit, while suppressing the increase of the sliding resistance the piston has with respect to the cylinder. The circumferential wall of the moving piston unit has a pair of skirt parts opposing each other across a piston boss and a pair of side-wall parts coupling the skirt parts and each having an outer circumferential surface concaved toward the central axis X1 of the piston. The side-wall parts have a penetration part each, which penetrates the side-wall part and extends in the directions the moving piston unit reciprocates with respect to the base piston unit. The base piston unit has rotation preventing projections that project perpendicular to the central axis of the piston and are inserted into the penetration parts.

摘要： A reed valve for opening and closing a discharge port of a compressor mechanism is provided with a protruding part which is formed at a distal end thereof to come in and out of the discharge port. The shape of the discharge port and the shape of the reed valve are determined such that flow passage areas S0, S1 and S2 at different parts of the discharge port satisfy S2≧S1≧S0 when the reed valve is lifted to a maximum level. Accordingly, a refrigerant is discharged through the discharge port without reducing the amount of flow of the refrigerant, thereby reducing loss of pressure.

摘要： A reed valve and a valve retainer for the reed valve are provided at a discharge port of a compression mechanism that compresses fluid. The valve retainer has a polymer actuator at an end part of a valve fixing part for fixing the reed valve. The polymer actuator expands or contracts in length to change a fixed length of the reed valve, thereby changing a rigidity of the reed valve. This attains appropriate control of responsiveness of the reed valve according to the volume.

摘要： A scroll fluid machine includes a stationary scroll having a spiral wrap formed on an end plate and a moving scroll having a spiral wrap formed on an end plate. A polymer actuator for adjusting the amount of space between the wrap and the end plate is disposed in a recess formed at a tip of the wrap. The polymer actuator changes its shape along a height of the wrap to adjust an amount of the space. The polymer actuator also functions as a seal between the end plate and the wrap. The recess is formed such that a wall of the recess including an inner circumference surface of the wrap has a thickness different from that of a wall of the recess including an outer circumference surface of the wrap.
