Abstract: A compressor has a housing body, a drive shaft, a swash plate, and a piston. The swash plate converts rotation of the drive shaft to reciprocating movement of the piston in a cylinder bore. The piston compresses gas supplied to the cylinder bore from an external circuit via a suction chamber and discharges the compressed gas to a discharge chamber. The swash plate is tiltable with respect to a plane perpendicular to the longitudinal axis of the drive shaft according to differential pressure between the crank chamber and the suction chamber. The swash plate controls the displacement of the compressor based on the inclination thereof. A spool is movable longitudinally between a first position and a second position in response to the inclination of the swash plate. The spool connects the external circuit with the suction chamber in the first position and disconnects the external circuit from the suction chamber in the second position. The housing body has a surface slidably engaged by the spool. A coating layer is provided on at least one of the spool and the slide surface to reduce frictional resistance occurring due to the sliding movement of the spool on the slide surface. A second coating layer is provided on an end surface of the spool to lubricate and thereby reduce frictional resistance with the housing surface along the periphery of the suction passage leading into the shutter chamber occurring due to rotation of the spool, and also to improve the seal between the end surface of the spool and the housing when in the second position closing off the suction passage.

Abstract: A compressor has a swash plate (15) tiltable between maximum and minimum inclining angles with respect to a plane perpendicular to an axis of a drive shaft (9) according to a difference between pressures in a crank chamber (2a) and a suction chamber (3a). An internal gas passage (2a, 3a, 3b, 30, 31) includes the crank chamber (2a), the suction chamber (3a) and a discharge chamber (3b). The internal gas passage is connected to an external circuit (35) separately provided from the compressor. The rotation of the drive shaft (9) is converted to a reciprocating movement of a piston (22) to vary a capacity of a cylinder bore (1a). The piston (22) compresses a gas supplied from the external circuit (35) to the internal gas passage (2a, 3a, 3b, 30, 31) and discharges the gas to the external circuit (35). A inhibiting apparatus (21, 28, 42; 21, 28, 57; 28, 58, 59, 60; 28, 61, 62, 63; 28, 64, 65, 66) inhibits the circulation of the gas through the internal gas passage (2a, 3a, 3b, 30, 31) and the external circuit (35) when the swash plate (15) is located between the minimum inclining angle and a first inclining angle. The first inclining angle is greater than the minimum inclining angle of the swash plate (15).

Abstract: The compressor is cooled by gas in the internal duct (26) connected selectively to an external coolant circuit (35). Its piston (22) reciprocates in a cylindrical bore (1a) through a two-part housing (2,3) surrounding a rotary shaft (9) which carries a whirling disc (15) movable between max. and min. angles of inclination.At min. inclination the internal duct is sepd. from the external circuit by a hollow cylindrical closure element (21). As the disc moves, the amt. of gas driven through the duct is restricted by a tapered projection (20).

Abstract: A refrigerant compressor having a drive shaft rotatable to cause compression of a refrigerant gas, and a drive power transmission unit for transmitting a drive power from an external drive power source to the drive shaft, the drive power transmission unit having a pulley freely rotatably mounted around the drive shaft, a power transmitting element fixed to the drive shaft, and a shock absorbent rubber element arranged between the pulley and the power transmitting element for providing a positive engagement between the rubber element and the pulley, and between the rubber element and the power transmitting element. The shock absorbent rubber element absorbs a change in a load torque applied to the compressor before the torque change is transmitted to the external drive power source via the pulley, and disengages from at least one of the pulley and the power transmitting element when an excessive load torque is applied to the compressor to interrupt transmission of the excessive load torque from the compressor to the external drive power source.

Abstract: PROBLEM TO BE SOLVED: To improve the blowing efficiency of a fan by providing a wall to regulate the in-flow of the outside air from a clearance at the position opposite to an outer circumferential side of the clearance formed between the fan and a fixing member on a housing side along the direction of the outside air flow. SOLUTION: A fan 46 is provided so as to be opposite to a front housing 1, and a cylindrical wall body 47 is arranged so as to surround the outer circumference of a front wall surface 1α of the front housing 1. An annular outer circumferential opening K1 of a clearance K between the fan 46 and the front wall surface l1α2 is surrounded by the wall body 47. The wall body 47 prevents the outside air in the vicinity of the outer circumferential opening K1 by the fan 46 from being sucked. As a result, the whole sucking capacity of the fan 46 can be demonstrated in forming the outside air flow in an air passage 44. The air blowing capacity of the fan 46 can be improved.

Abstract: PROBLEM TO BE SOLVED: To realize a compressor that is able to check any large-size trend due to a construction for cooling a heating element in housing. SOLUTION: An air space of an opening part 7β in a boss part 7 doubles as a fresh-air inlet 42 for inducing fresh air into a lip seal 12 set up innermostly in this boss part 7. A fresh-air outlet 43 guiding the fresh-air induced into the lip seal 12 to the outside is installed piercingly in a peripheral wall of the boss part 7. Two notches 14α and 16α are formed in a corresponding position of the fresh air outlet 43 at both first and second lip fittings 14 and 16. In succession, the fresh-air inlet 42 and the fresh-air outlet 43 are connected to each other via these notches 14α and 16α, whereby a vent passage 44 is constituted. A fresh-air inlet 45 or an oblique hole is installed in a pulley 9, forming a fresh-air current in the vent passage 44 by means of rotation of this pulley 9.
