摘要： A swash plate compressor includes a cylinder block having positioned therein a plurality of cylinders and a crank chamber. Each of a plurality of pistons has a head portion and a skirt portion. The head portion of the piston is slidably disposed within one of the cylinders. The skirt portion of the piston slidably abuts on an inside surface of the crank chamber, and by its action the pistons are prevented from nutating axes when the pistons are driven in a reciprocating motion within the cylinders upon rotation of the swash plate. The crank chamber has a truncated cone-shape, the inside diameter of which is reduced between a top dead center and a bottom dead center of the piston. The structure for the swash plate compressor according to this invention reduces vibration and noise caused by the nutation of the pistons.

摘要： The object of the present invention is to offer not only a compressor which is compact and reduced in weight, but also its piston whose neck portion is increased in strength at a time. A single-headed piston for a swash plate type compressor has a hollow head portion, a pair of engaged portions engaged with a swash plate, and a neck portion connected to the pair of the engaged portions at the outer peripheral side of the swash plate. The pair of the engaged portions sandwiches both of the outer peripheral end surfaces of the swash plate through a pair of hemispherical shoes. A pair of concave portions having a pair of concave spherical surfaces is formed on the surfaces facing each other of the pair of the engaged portions so as to receive a convex spherical surfaces of shoes slidably. The pair of concave portions have a common spherical center. The spherical center is positioned on the plane which includes the central axis of the head portion and is parallel in the extending direction of the pair of the engaged portions, and is positioned deviatedly to the opposite side (to the radially inner side of the compressor) to the neck portion from the central axis of the head portion. It is desired that the spherical center is positioned deviatedly to the radially inner side of the compressor by equal to or greater than {fraction (1/30)} of the diameter of the head portion. The thickness of the neck portion is increased, and the bending strength of the neck portion is improved. In addition, the diameter of the swash plate is to be compact. Therefore, the compressor is reduced in weight, and is improved in its durability.

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

摘要： The piston (1) has a ball receptacle (14) for the rod head (4) of the piston rod (2) of a swash plate compressor. For absorbing particularly high pressures the rod head (4) has a relatively large diameter, so that the ball receptacle (14) extends close to the circumference of the piston (1). The piston wall (15) laterally surrounding the rod head (4) has a circumferential indentation (21) which, in the inwards direction, forms an uninterrupted undercut enclosing the spherical rod head (4).

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 swash plate (3, 18) and pistons (6, 17) included in a swash plate type compressor are made of an aluminum alloy as a base material. Rotation-preventive interfering surfaces (6d, 17d) of the pistons (6, 17) which interfere with another member to restrain the pistons from rotation about their axes are coated with a film of a solid lubricant. Sliding contact surfaces (6a, 17a) of the pistons (6, 17) in sliding contact with surfaces defining cylinder bores (5, 16) are coated with a film of a solid lubricant. When the rotation-preventive interfering surfaces (6d) of the pistons (6) come into impulsive contact with the outer circumference (3b) of the swash plate (3), the outer circumference (3b) of the swash plate (3) is coated with a lubricating film.

摘要： A piston for use in a compressor that compresses gas containing lubricating oil is disclosed. The compressor has a crank chamber and cylinder bores for accommodating the pistons. A swash plate is located in the crank chamber and is supported on a drive shaft for integrally rotating with the drive shaft. The swash plate is operably connected to the pistons by shoes to convert the rotation of the drive shaft to reciprocation of each piston. Each piston has a head for compressing the gas supplied to the cylinder bore and a skirt projecting from the head toward the crank chamber. The skirt has a slot for receiving the swash plate by means of the shoes. A rib is formed on an inner wall of the slot and extends parallel to the axis of the piston. When the swash plate rotates, swirling gas in the crank chamber collides against the rib. When the gas collides against the rib, the oil contained in the gas separates from the gas and is guided to the shoes.
