摘要： In a reciprocating compressor, an adequate lubricating effect is ensured for a sliding surface between a piston and a cylinder bore, and the leakage of a refrigerant for discharge is prevented. After a lubricating oil mixed within the refrigerant is separated by an oil separator 23 on a discharge side, the separated lubricating oil is guided via an oil supply hole 29 in a cylinder block 1 to the sliding surface between the cylinder bore 12 and the piston 13 that reciprocates within the cylinder bore 12 thereof in order to lubricate the surface. In this reciprocating compressor, the intermediate axial portion of the outer circumference of the piston 13 has a small diameter in order to define an oil sump 30. The oil sump 30 is configured so as not to directly communicate with a drive chamber 7, and oil always collects within the oil sump 30.

摘要： A fuel cell system including a fuel cell having an air feeding tube, an air discharging tube and a fuel feeding tube, the air discharged from the fuel cell through the air discharging tube containing water. The system also includes a compressor, a water separation tank, and a water supply passage for supplying water collected in the water separation tank to the compressor. When the system is to be stopped, the water supply passage is first blocked while the compressor is operating. The humidity or the temperature of the process air is then detected, and the compressor is stopped when the detected humidity is lower than a predetermined value, or when the detected temperature is higher than a predetermined value.

摘要： An improved scroll compressor having a movable scroll that orbits without being inclined. The compressor has a fixed scroll formed in the housing. The movable scroll is accommodated in the housing and mates with the fixed scroll. The movable scroll is driven by a drive shaft via a crank mechanism. A flange is formed at the periphery of the movable scroll and lies perpendicular to the drive shaft. A groove is formed in the housing. The groove is slightly wider than the thickness of the flange. The flange is slidably accommodated in the groove. Support holes extend through the flange. A pin is supported in each support hole. The ends of each pin are received in guide holes. Since engagement of the flange and the groove prevents the movable scroll from being inclined, the pin is maintained parallel to the guide holes and follows the wall of the guide holes. As a result, uneven wear of the pins and the guide holes is avoided.

摘要： A wave cam 17 is rotatably supported by a drive shaft 13 in cylinder blocks 11, 12. Front and rear cam surfaces 17A, 17B of the wave cam 17 are defined by the surface of a predetermined imaginary cylindroid. Semi-spherical shoes 18, 19 are interposed between each cam surface 17A, 17B and each double-headed piston 16, which is accommodated in each cylinder bore 11a, 12a. Each shoe 18, 19 has a spherical surface 18a, 19a and a flat surface 18b, 19b. An imaginary circumference C0 corresponding to the arrangement of centers Q1, Q2 of the spherical surfaces 18a, 19a of the shoes 18, 19, respectively, is defined on each cam surface 17A, 17B. An imaginary circumference C1 corresponding to the arrangement of axes L1 of each cylinder bore 11a, 12a is also defined on each cam surface 17A, 17B. The center of both circumferences C0, C1 coincide with an axis L0 of the drive shaft 13. The radius R1 of the circumference C0 is larger than the radius of the circumference C1. Integral rotation of the drive shaft 13 and the wave cam 17 reciprocates each piston 16 in the cylinder bores 11a, 12a via the shoes. The centers Q1, Q2 of each spherical surface orbits outside of the circumference C1 on the associated cam surface 17A, 17B.

摘要： A wave cam type compressor includes cylinder blocks. A drive shaft is rotatably supported in the center cylinder blocks. A plurality of cylinder bores are defined about the drive shaft in the cylinder blocks. A wave cam, mounted on the drive shaft, comprises opposing cam surfaces. A width of second portions which move a piston to its bottom dead center position is more narrow than a width of first portions which move a piston to its top dead center position. The pistons are connected to the wave cam by way of shoes. The shoes move along a predetermined path on the cam surfaces. The shoes and the wave cam convert the integral rotation of the drive shaft and wave cam to a reciprocating movement of the pistons to compress fluid introduced into the cylinder bores.

The ends of each bore are covered with a pair of housings. The bores communicate with discharge chambers. A drive shaft is rotatably placed within the cylinder blocks. A swash plate is rotatable in the crank case, and is mounted on the drive shaft. A plurality of pistons are drivably coupled to the swash plate, and are reciprocotable in their respective bores. As the pistons reciprocate, a refrigerant in the crank case is sucked into each bore and is compressed therein. The compressed refrigerant is discharged into the discharge chambers from the bores.
