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： 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 fluid compressor including a housing, a pair of scroll elements 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 and are formed with a groove on the end surface of each wrap means which receives a seal element. Each groove is formed with its center line inward of the center line of its respective spiral wrap. This construction prevents the walls of the groove from prematurely deteriorating and causing attendant destruction of the scroll elements.

摘要： A reciprocating piston type refrigerant compressor includes a compressor 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 wobble plate driven by a cam rotor mounted on a drive shaft. The cam rotor includes an adjustable slant plate with a sloping surface at an adjustable slant angle in close proximity to the wobble plate. Accordingly, the stroke of the pistons within the cylinders can be changed by adjusting the slant angle of the sloping surface. The slant angle of the sloping surface is adjusted in response to the change of pressure in the crank chamber. The crank chamber communicates with the suction chamber through a passageway and a valve control mechanism controls the opening and closing of the passageway. Thus, the capacity of the compressor of the present invention can be adjusted by changing the slant angle of the sloping surface of the slant plate in response to operation of the valve control mechanism.

摘要： A scroll-type fluid displacement apparatus is disclosed having a pair of scroll members each comprising an end plate and a spiral wrap extending from one side of the end plate. The spiral wraps interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of sealed-off fluid pockets. At least one of the scroll members has a discharge port or fluid hole near the center of the spiral element and is provided with an anti-wear plate on its end surface facing the other scroll member. The anti-wear plate is an involute plate that covers substantially the area of the end surface of the end plate on which the spiral wrap of the other scroll member makes contact during the orbital motion of the orbiting scroll member. The radially inner end of the anti-wear plate is spaced from the discharge port to avoid blocking the discharge flow or covering the discharge port. Therefore, the undesirable vibration of the anti-wear plate by fluid flowing through the port is avoided.

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 is disclosed. The apparatus includes a housing. A fixed scroll member is fixedly disposed within the housing and comprises a first end plate means from which a first wrap means extends. An orbiting scroll member comprises a second end plate means from which a second wrap means extends, and is supported for orbiting motion within the housing. Both wrap means interfit at an angular and radial offset to make a plurality of line contacts to define at least one pair of symmetrically disposed, sealed off fluid pockets. The first end plate means is formed with two holes which are placed at symmetrical positions to be simultaneously closed by the axial end surface of the second wrap means. These two holes are connected to one another by a passage means. The pressure in the sealed off fluid pockets is thereby equalized at the time the pockets are sealed.
