摘要： A scroll-type fluid displacement apparatus, in particular, a compressor unit is disclosed. The unit includes a housing with a fluid inlet port and a fluid outlet port. A fixed scroll with first end plate and first spiral element is fixedly disposed in the housing. An orbiting scroll with a second end plate and a second spiral element is disposed for orbiting motion in the housing. The first and second spiral elements interfit with one another at an angular offset to make a plurality of line contacts to define at least one pair of sealed off fluid pockets. A drive pin extends from an inner end of a drive shaft. The orbiting scroll has a boss which rotatably supports a bushing. An eccentric hole is formed in the bushing and the drive pin is received within this hole. The center of the drive pin is located on an opposite side to the center of the drive shaft with regard to a straight line, which passes through the center of the bushing and is perpendicular to a connecting line passing through the center of the drive shaft and the center of the bushing. The center of the drive pin also is beyond the connecting line in the direction of rotation of the drive shaft. The bushing has a balance weight for cancelling a centrifugal force which arises because of the orbiting motion of the scroll member and bushing. Dynamic balance is accomplished by the use of a pair of balance weights affixed to the drive shaft for generating a moment of the same amount, but opposite in direction, to the moment generated by a force due to the interaction of the centrifugal force of the orbiting parts and the first balance weight.

摘要： A scroll type compressor unit including a compressor housing having fluid inlet and outlet ports, and two fixed and orbiting scroll members within the compressor housing. Each scroll member has an end plate and a spiral element which are maintained angularly and radially offset so that both spiral elements interfit with a line contacts between the spiral curved surfaces to define moving sealed off pockets. In order that the fluid may be reliably taken into all fluid pockets, the end plate of the fixed scroll member is formed with a suction port connecting to the fluid inlet port at a position adjacent to the outer terminal end of the orbiting spiral element. Thus, the fluid introduced through the suction port may be taken into a fluid pocket which is formed at the outer terminal end portion of the orbiting spiral element and is sent along the outer surface of the orbiting spiral element to a fluid pocket which is formed at the outer terminal end of the fixed spiral element. The fixed spiral element is formed so that its outer terminal end engages with the inner surface of the compressor housing, and a seal plate member is disposed to close the gap between the inner surface of the housing and the peripheral surface of the orbiting end plate. This permits the fluid sent to the outer terminal end portion of the fixed spiral element to be pre-compressed.

摘要： A reciprocating piston type refrigerant compressor is disclosed. The compressor includes a housing having a cylinder block provided with a plurality of cylinders and a crank chamber adjacent the cylinder block. A piston slides within each cylinder and is reciprocated by a drive mechanism which includes a rotary drive shaft, a rotor mounted on the drive shaft, and a coupling mechanism which converts the rotary motion of the rotor into the reciprocating motion of the pistons. The coupling mechanism includes an inclined member which has an inclined surface disposed at an adjustable incline angle. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the incline angle of the inclined surface in response to the change of pressure in the crank chamber. A spring applies a force to urge the inclined surface to a decreased incline angle when th incline angle is greater than a predetermined incline angle, but applies no force when the angle is less incline than the predetermined incline angle.

摘要： In a scroll type fluid compressor having an orbiting scroll member and a fixed scroll member which form at least one pair of outer fluid pockets and a central pocket therebetween for fluid compression, the axial end surfaces of each spiral element of the scroll members have a groove along the spiral curve. At least one closed portion is located along the groove to block fluid flow in the groove. A seal element is loosely fitted in the groove. During operation the compressed fluid flows into the groove to urge the seal element against the end plate of the opposite scroll member so that the axial sealing between the spiral element and the end plate is assured without leakage of fluid along the groove. Also, the closed portion is located along the spiral element at the location where the line contact point where the outer fluid pockets and the central pocket merge to prevent back pressure changes from causing excessive wear of the seal element.

摘要： A scroll type fluid displacement apparatus including a housing, a pair of scroll members each comprising an end plate and a spiral wrap means projecting from one surface of the end plate. Both wrap means are interfitted to make a plurality of line contacts between them, and a driving mechanism including a drive shaft is connected to one of the scroll members to effect orbital motion thereof relative to the other (fixed) scroll member while rotation of the orbiting scroll is prevented. The center portions of the wrap means are made thicker than the remaining portions thereof, the center portions extending substantially from the inner ends of the wrap means outwardly at least throughout the portions thereof which contact one another when the two innermost fluid pockets are merged into a single fluid pocket to form the high pressure space near the center of the scroll members. This construction insures sealing of the high pressure space from adjacent fluid pockets, keeping volumetric efficiency and horsepower requirement of the unit to a certain level under a limited accuracy of machining of the spiral elements.
