摘要： A removable sealing plug device for protecting the interior of a refrigerant compressor from dust, dirt, and corrosion during storage and/or transport of the compressor before it is assembled into a refrigerating system, including a plug element made of a rubber material and having a body portion suitable for being sealingly fitted in an inlet and/or outlet port of the compressor and a columnar head portion formed in an upper face of the body portion, and a base plate having a through-hole in which the columnar head of the plug element is press-fitted, the through-hole of the base plate being provided with sawtooth-like projections to non-removably hold the columnar portion of the plug element and secure it to the outer portion of the compressor, by using an existing threaded hole and a screw bolt, to hold the plug element between the base plate element and the outer circumference of the compressor. The plug element and the base plate of the sealing plug device are concurrently removed from the inlet port and/or outlet port of the compressor due to a tight engagement of the plug element and the base plate provided by the sawtooth-like projections.

摘要： A wave cam type compressor is described. Cylindroid blocks are provided to support a drive shaft and to contain a plurality of cylinder bores centered around the drive shaft. A wave cam attached to the drive shaft has cam surfaces on the front side and the rear side. The cam surfaces are composed of convex surfaces only. Pistons in the cylindroid blocks are operated by the wave cam through shoes. Each shoe has a spherical surface and a flat surface. The spherical surface is fitted in a recess formed on the piston, while the flat surface makes line contact with the cam surface of the wave cam. The shoes move relative to the wave cam on a predetermined circular path on the cam surfaces. The rotation of the wave cam together with the drive shaft is converted to reciprocating motions of the pistons in the cylinder bores with the aid of the shoes and wave cam, thus achieving compression of a fluid supplied to the cylinder bores.

摘要： A swash-plate type compressor comprising a cylinder block, front and rear valve plates, and front and rear housings attached to either end of the cylinder block over the valve plates. A swash-plate is accommodated in the cylinder block to reciprocally move a plurality of double headed pistons which form compression chambers on either side thereof. A drive shaft carries the swash-plate and is supported by a pair of tapered roller bearings. Each of the tapered roller bearings is secured in the central hole of each valve plate. Also, each valve plate is coupled to the cylinder block in a locating projection-locating hole fitting relationship to effect centering the drive shaft relative to the cylinder block. In addition, a suction passage is arranged to introduce the refrigerating gas from the swash-plate chamber to each of the compression chambers in such a manner as to reduce the radius of the cylinder block.

摘要： The durability of a coating layer formed on the sliding surface between two members of a compressor, and the sliding contact between the two members, is kept excellent over a long period of time. In a peripheral portion 10d of a swash plate 10, a pair of shoes 20 are connected to the swash plate 10 while intervening between the swash plate 10 and a piston 8. Both the swash plate 10 and the shoes 20 are formed from an iron series material. A film 23 is formed on both surfaces 22 of the peripheral portion 10d of the swash plate 10, and the shoes 20 slide on the film 23 on the swash plate 10. The film 23 is a coating layer formed from a resin containing metallic particles. The particle size of the metallic particles is larger than the thickness of the film 23 (e.g., from 10 to 100 &mgr;m), and the surface of the film 23 is made smooth by polishing. The resin functioning as a binder of the metallic particles is formed from, for example, a polyimide resin.

摘要： A compressor comprises a cylinder block having cylinder bores formed radially spaced from and circumferentially distributed equidistantly about the cylinder longitudinal axis. Pistons are slidably received in the respective bores for reciprocation therein executing alternately suction and discharge strokes. The compressor also has a discharge valve assembly for controlling discharge of a compressed fluid from each of the bores into a discharge chamber, which assembly is axially movable between a first position in which the assembly is abutted against an end wall of the block and a second position in which the assembly is spaced from the end wall of the block to define a narrow space therebetween to interconnect the bores with each other. When the assembly is pushed toward the second position by the pressure of the compressed fluid during initial running of the compressor, bypass channels interconnect the cylinder with the discharge chamber.

摘要： A compressor has a plurality of cylinder bores defined around a rotary shaft in a cylinder block and a plurality of double-headed pistons accommodated in the respective cylinder bores. The pistons compress refrigerant gas in a plurality of front and rear compression chambers defined in the bores in the front and rear of the respective pistons according to the rotation of a cam plate mounted on the rotary shaft. The compressor has bearing that receive thrust loads applied to the rotary shaft during operation of the compressor. The pistons create a net thrust load determined by the difference between the maximum of the sum of loads applied to the front sides of the pistons by the refrigerant gas in the front compression chambers and the maximum of the sum of loads applied to the rear sides of the pistons by the refrigerant gas in the rear compression chambers. The pistons transfer the net thrust load to the rotary shaft in a predetermined direction.

摘要： A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.

摘要： A rotary valve is supported on a rotary shaft for an integral rotation. The rotary valve has a suction passage and a discharge passage. The suction passage connects a cylinder bore with a suction chamber according to the rotation of the rotary valve when a piston is in the suction stroke. The discharge passage connects the cylinder bore with a discharge chamber according to the rotation of the rotary valve when the piston is in the discharge stroke. The discharge passage includes a first passage and a second passage. The second passage communicates with the cylinder bore after the first passage has communicated with the cylinder bore after the first passage has communicated with the cylinder bore according to the rotation of the rotary valve. A discharge valve is mounted on the rotary valve. The discharge valve selectively opens and closes the first passage according to the difference between the pressures in the cylinder bore and in the discharge chamber.
