摘要： Disclosed is a compressor having a plate rotatable about an axis of a rotary shaft and a piston connected to the plate, wherein the plate causes the piston to reciprocate between a top dead center and a bottom dead center of its stroke in accordance with the rotation movement of the plate. A cam surface is provided with the plate for actuating the piston. A shoe engages with the plate for transmitting the rotation movement of the plate to the piston. A recess is formed on the piston for restricting rolling of the shoe on the plate for causing the shoe to slide on the plate to reduce the pressure caused by the contact between the cam surface and the shoe.

摘要： A double-headed piston type compressor has a disk plate. The disk plate is rotatably supported on a drive shaft for driving each piston along a reciprocating path. The plate is curved in a single direction to form a solid cam on its surface. The cam transforms a single rotation of the plate into two reciprocating movements of the piston. Cam followers provided between the plate and the piston are formed to be conform with the shape of the cam. The cam followers contact and roll on the piston, and slide on the cam.

摘要： A wave cam type compressor is provided. The compressor has a wave cam body mounted on a rotary shaft for integral rotation and pistons operably contacting said cam body by way of shoes. The shoes are moveable relative to the cam body according to the rotation of the cam body. The shoes move on predetermined paths on cam surfaces of the cam body. The rotation therewith of the rotary shaft is converted into a reciprocation movement of the pistons between top dead center and a lower dead center in cylinder bores to compress fluid supplied into the cylinder bores. Each cam surface has a contour matching the locus of a predetermined smooth two-dimensional imaginary curve when the curve is translated from its plane in the direction perpendicular to the plane. A first portion is provided on the cam surface to drive the piston to the bottom dead center and a second portion is provided on the cam surface to drive the piston to the top dead center. The second portion has a greater radius of curvature than the first portion.

摘要： A multistage compressor for compressing a refrigerant for an automobile air conditioning system includes a body which has a front housing and a rear housing connected to each other with a cylinder block clamped therebetween. The cylinder block includes a plurality of sets of cylinder bores arranged parallel to, and around the longitudinal axis. Pistons are received within the cylinder bores to define a plurality of sets of compression chambers together with the walls of the cylinder bores. The sets of the compression chambers are fluidly connected to each other to provide a series of stages for compressing the refrigerant gas. The cylinder bores are arranged at equal angles around the longitudinal axis in each set of the compression chambers whereby the unbalanced force on the swash plate and the drive shaft is removed.

摘要： A scroll type compressor has a fixed scroll in a housing and a movable scroll opposed to the fixed scroll to define a compression chamber with the fixed scroll. Gas introduced into a suction chamber via an inlet is compressed in the compression chamber and then is discharged to a discharge chamber via a discharge port to exhaust the compressed gas from an outlet to the outside of the compressor in accordance with the circular movement of the movable scroll. A part of the discharge chamber is defined in the fixed scroll. An outlet flange protrudes from the fixed scroll. The outlet flange includes the outlet which communicates with the discharge chamber.

摘要： A rotary compressor for compressing a refrigerant gas has a by-pass port and a control valve means. The by-pass port communicates at one end with a suction chamber containing the gas to be compressed, and at the other end with a compression chamber wherein compression of the refrigerant gas is in progress. The control valve means includes a valve spool accommodated in a chamber formed in a front side plate of the compressor and movable between its full-load position, where a gas suction port is opened to the compression chamber while the by-pass port is closed, and its partial-load position where the former is at least partially closed while the latter is opened. The valve spool is normally biased to its partial-load position. During operation of the compressor, the valve spool is placed under the influence of a first pressure of the gas acting to urge the same towards its said full-load position, and to a second pressure of the gas to urge the same towards its said partial-load position. The spool is shifted automatically to its partial-load position when the difference between these first and second pressures is decreased with a drop of cooling load. The compressor of the invention further comprises a flow control means for regulating the flow of the gas into its compression chambers in the event of a rapid increase of compressor speed.

摘要： A compressor has a casing and a compressing member located within the casing. A gas drawn from a suction chamber into a compression chamber is compressed to be discharged to a discharge chamber in accordance with the operation of the compressing member. The compressor has a drive apparatus located within the casing for driving the compressing member. The drive apparatus has a fixed drive member fixed to the casing and having a plurality of electrode strips arranged in a single direction with a predetermined pitch. A second member is fixed to the compressing member. The compressing member is driven by relative movement generated between the fixed and movable drive members in response to Coulomb force generated between the fixed and movable drive members when voltage is applied to the electrode strips.
