摘要： In a piston type compressor, a housing includes a cylinder block that forms plural cylinder bores and an accommodating hole at a center thereof. The valve port assembly connected to the cylinder block includes suction and discharge ports, suction and discharge valves made of flapper valves. An end portion of the drive shaft rotatably supported by the housing is slidably accommodated in the accommodating hole. The piston in each cylinder bore and the valve port assembly form a compression chamber. The cylinder block forms therein communication holes that connect each compression chamber to the end portion that forms therein a residual gas bypass passage. The residual gas bypass passage connects one communication hole, which communicates with the high-pressure side compression chamber that has finished discharge process of gas, to another communication hole, which communicates with the compression chamber that is lower in pressure than the high-pressure side compression chamber.

摘要： A piston compressor includes a rotary valve having a suction guide hole. A plurality of introducing passages are formed in a cylinder block to connect compression chambers to the rotary valve. The inner circumferential surface of each cylinder bore has a suction auxiliary recess, which is connected to the outlet of the corresponding introducing passage in the circumferential direction of the cylinder bore at the end of the cylinder bore facing a valve assembly. Therefore, the compressor reduces suction resistance of gas at the beginning of the suction stroke without enlarging introducing passages formed in the cylinder block.

摘要： An airtight compressor includes a compression mechanism disposed inside an airtight container in a position below a gas retention space. An oil supply passage supplies oil from an oil reservoir both to the gas retention space (14) and to a sliding portion of the compression mechanism in a compression space. The oil supply passage communicates the gas retention space with a second space located on an opposite side of the piston from the intake chamber. A second channel is a channel that is different from the oil supply passage. The second channel enables a gas medium to flow from the gas retention space to the second space. Preferably, passage resistance when the gas medium flows through the second channel is less than when the gas medium flows through the oil supply passage.

摘要： The present invention provides a screw compressor wherein, even if a gate rotor flexes owing to a temperature differential between a casing and a screw rotor during operation of a compressor, the gate rotor is prevented, with a simple configuration, from biting into the screw rotor, which reduces the amount of wear of the gate rotor and prevents a decline in the compressor's performance. The gate rotor (3) comprises a gate rotor main body (30) and a shaft (40) to which the gate rotor main body (30) is attached. An elastic body (5) is disposed between (S) the axle (41) of the shaft (40) and the hole (32) of the gate rotor main body (30).

摘要： A rotary compressor includes a fixed side and a movable side that is eccentrically movable relative to the fixed side. The movable side moves in response to operation of a drive mechanism, which rotates a drive shaft. The fixed side has a main bearing formed as a unitary part. A cylinder may serve as the movable side, which is coupled through an eccentric part to the drive shaft. The drive shaft is supported by the main bearing. With such an arrangement, a ring-shaped piston may serve as the fixed side, which is formed integrally with the main bearing in a front head.

摘要： A motor rotor for a compressor includes a rotor core, at least one gas passage and an oil passage. The rotor core is configured to rotate about a rotation axis and has a plurality of stacked steel plates. The gas passage penetrates the rotor core in its axial direction and allows a gas fluid to flow therethrough from a first axial direction end portion of the rotor core to a second axial direction end portion on the opposite axial side. The oil passage is positioned radially outwardly of the gas passage inside the rotor core relative to the rotation axis. The oil passage allows oil to flow from the second axial direction end portion to the first axial direction end portion, which is opposite to the gas flow direction through the gas passage.
