摘要： A heat insulating structure in a piston type compressor includes a heat insulating member. The piston type compressor includes a cylinder block and a cover housing connected to the cylinder block, a piston is accommodated in a cylinder bore defined in the cylinder block to define a compression chamber. A suction pressure region and a discharge pressure region are defined in the cover housing. The piston is reciprocated in the cylinder bore in accordance with rotation of a rotary shaft so that refrigerant gas is drawn from the suction pressure region to the compression chamber and discharged from the compression chamber to the discharge pressure region. The heat insulating member has a predetermined shape and is located in the cylinder block. The heat insulating member has an inner peripheral surface that defines the cylinder bore.

摘要： A gasket is provided between a cylinder block and a valve plate. By providing a through hole at a position near the center of the gasket, bending moment acting on the cylinder block is reduced, and hence deformation of the cylinder block is restrained. As a result, reciprocating motion of a piston and rotational motion of a rotary valve are performed smoothly.

摘要： A single headed piston type refrigerant compressor having a cylinder block forming therein a plurality of cylinder bores receiving a plurality of single-headed pistons for reciprocation therein, and a front housing joined to the cylinder block to define a crank chamber for receiving therein a cam plate. An extended bore-forming portion of the cylinder block having partial cylindrical guide surfaces each being continuous with the corresponding cylinder bore and capable of being in slide contact with the piston head portion of the single-headed piston and the outer circumference of a shoe-holding portion of the single-headed piston is formed by extending a peripheral portion of a front end of the cylinder block into the crank chamber. A projecting portion formed on each single head piston protrudes from a side end surface of the shoe-holding portion extending behind the piston head portion into the crank chamber. Therefore, the extended bore-forming portion can additionally be extended toward the crank chamber by a length corresponding to the distance of dislocation of the projecting portion into a space on the front side of the crank chamber to increase additionally the length of contact of the piston with cylinder bore.

摘要： A compressor comprises a piston having a piston head and an engaging portion, said piston head being inserted into a cylinder bore, said engaging portion having a piston guide and a shoe seat in which a shoe is incorporated, wherein said shoe is engaged with a swash plate. The piston reciprocates in correspondence to rotation of the swash plate and the piston head compressing a refrigerant by the reciprocal movement. The piston guide protrudes outward from the surface of the piston head, extending over said shoe seat, being formed with dimensions exceeding the corresponding shoe seat and being caused to reciprocate along the inner wall surface of said housing in line with reciprocation of said piston.

摘要： A compressor includes a piston (26) reciprocating in a cylinder bore (25). The piston (26) draws refrigerant into and discharges refrigerant from a compression chamber (36) , which is formed between the piston (26) and a valve plate (14). The valve plate (14) has a discharge port (32) connecting the compression chamber (36) to the discharge chamber (17). A guide passage (41) facilitates the flow of the refrigerant from the compression chamber (36) to the discharge port (32). The guide passage (41) is defined in the compression chamber (36) when the piston (26) is located at the top dead center position. This decreases pressure losses that would otherwise occur when the piston (26) is near the top dead center position.
