Abstract: A variable capacity rotary compressor to prevent an eccentric bush and a locking pin from being deformed or worn out due to a variance in a pressure of a compression chamber as a rotating shaft rotates. The compressor includes upper and lower compression chambers having different interior capacities thereof, and a rotating shaft. Upper and lower eccentric cams are provided on the rotating shaft to be eccentric from the rotating shaft in a common direction. Upper and lower eccentric bushes are fitted over the upper and lower eccentric cams, respectively, with a slot provided at a position between the upper and lower eccentric bushes. The locking pin operates to change a position of the upper or lower eccentric bush to a maximum eccentric position. Further, surfaces of parts around first and second ends of the slot are heat-treated, thus increasing a hardness thereof.

Abstract: A scroll type fluid compressor with a capacity adjusting mechanism is disclosed. The compressor includes a housing, a first fluid inlet port, a second fluid inlet port and a fluid outlet port. A fixed scroll member is disposed within the housing and has a circular end plate from which a first wrap extends. The end plate of the fixed scroll member partitions the inner chamber of the housing into a front chamber and a rear chamber. The rear chamber is divided into a discharge chamber connected to the fluid outlet port, a first suction chamber connected to the first fluid inlet port and a second suction chamber connected to the second fluid inlet port. An orbiting scroll member is disposed in the front chamber and also has a circular end plate from which a second wrap extends. Both wraps interfit at angular and radial offsets to form a plurality of line contacts to define at least one pair of sealed off fluid pockets. The end plate of the fixed scroll member has a hole at an outer peripheral portion thereof which connects the first suction chamber to the front chamber. The end plate also has a pair of holes which are placed at symmetrical positions and which connect the fluid pockets to the second suction chamber. Valve means is disposed in the communication line between the external fluid circuit and the connecting line of the first and second inlet ports to sectively control the connection therebetween.

Abstract: Compression of water vapour as R718 is disclosed with and without addition of additives as an aqueous solution in rotational displacement machines, i.e. refrigeration, air-conditioning and heat pump technology. To largely avoid over or under-compression, it is proposed for the easiest possible adaptation of the currently effective internal volume ratio as so-called iV value in the displacer that the compressor housing starting from the outlet side with rotor profile length LR over a length LiV comprises planar, i.e. flat iV disks (3j) with the index j for 1≤j≤n; n is the number of disks; n≥1 with a width bj per iV disk having planar surfaces PF preferably perpendicular to the neutral axis AN. The iV disks are displaced in a targeted manner individually by movement control devices (5j) per iV disk in each case by a distance si where 0

Abstract: In a gas compressor, an outline shape of an inner peripheral surface (41) of a cylinder (40) is set such that in a point before a first compression chamber (43B) adjacent to a second compression chamber (43A) in an upstream side in a rotational direction (W) is exposed to a discharge hole (45b) of a primary discharge portion (45) with rotation of a rotor (50) in the rotational direction (W) (point where the first compression chamber (43B) is positioned upstream of an angular position of being exposed to the discharge hole (45b) of the primary discharge portion (45)), a pressure of refrigerant gas (G) inside the compression chamber (43) reaches a discharge pressure. Therefore, the discharge hole (45b) of the primary discharge portion (45) always discharges the refrigerant gas (G) from the compression chamber (43).

Abstract: A claw pump includes: a housing; two rotating shafts which are disposed parallel; a pair of rotors respectively fixed to the two rotating shafts; a rotary drive device driving the pair of rotors; and a suction port and discharge ports formed in a partition wall of the housing. The discharge ports are constituted by a first discharge port and a second discharge port. The first discharge port is formed at a position that communicates with an initial stage compression space formed at an initial stage of a compression stroke in a compression space that is formed by joining a first pocket and a second pocket. The claw pump includes an opening/closing mechanism which opens the first discharge port when a pressure of the initial stage compression space reaches a threshold and closes the first discharge port when the pressure does not reach the threshold.

Abstract: A variable capacity screw compressor for use in a refrigeration system is provided. Compressed refrigerant gas from the compressor is expelled into a discharge port in fluid communication with the refrigeration circuit. The volume associated with the discharge port can be periodically varied, allowing the efficiency of the compressor to be varied periodically. The discharge port volume includes a penetration that houses a movable member or plug that permits the volume to be periodically varied. This movable member is accessible from the exterior of the compressor housing to adjust the position of the movable member within the discharge port volume. The movable member may be adjusted to a full open position in which the discharge port volume is maximized, to a full closed position in which the discharge port volume is minimized, and to any position between full open and full closed.

Abstract: A compressor includes orbiting and non-orbiting scroll members meshingly engaged to form a series of compression pockets, including first pockets when the orbiting scroll member is in a first position. A first porting in the non-orbiting scroll member communicates with the first pockets during a portion of a compression cycle. The first pockets include a set of radially outermost pockets located radially inward relative to the first porting and isolated from communication with the first porting during the compression cycle. The first porting is aligned with a spiral wrap of the orbiting scroll member at a location radially outward from and directly adjacent the first pockets when the orbiting scroll member is in the first position. Additional porting communicates with each of the compression pockets located radially outward relative to the first pockets when the orbiting scroll member is in the first position.

Abstract: A scroll compressor has a stepped wrap such that there is a greater height outer portion and a lesser height more central portion. Bypass ports are associated with the transition zone between the higher and lesser height portions. By providing the bypass port in a stepped scroll compressor, greater reductions in capacity can be achieved than have been provided in the prior art.
