Definitions

  • the present invention relates to a part of a compressor to be formed with a film and a method of forming the film on the part.
  • a method of coating a paint for lubrication on a part, such as the swash plate or the piston of a compressor, to be formed with a film is disclosed in Japanese Unexamined Patent Publications (Kokai) Nos. 10-26081 and 11-173263.
  • a paint is attached on the peripheral surface of a metal roller and then transferred to the peripheral surface of a rubber roller, and the paint transferred to the peripheral surface of the rubber roller is coated on the part to be formed with a film.
  • the metal roller and the rubber roller are in sliding contact with each other, and so are the rubber roller and the part to be formed with a film.
  • the paint attached on the metal roller is reduced to a predetermined thickness by being passed between a comma roller and the metal roller before being transferred to the rubber roller.
  • particle if caught in the gap between the comma roller and the metal roller, generates a streak on the paint film that has passed between the comma roller and the metal roller. This streak is transferred also to the film formed by being coated on the part to be formed with a film thereby to deteriorate the quality of the film. Unless the particle is removed, the streak is generated on all the films subsequently formed on the part to be formed with the film.
  • the film is liable to be wrinkled by the ununiform deformation of the pad.
  • the air may be sealed in and make it impossible to form a satisfactory film.
  • the force of pressing the pad against the part to be formed with a film increases toward the center of the particular surface of the pad, thereby making an ununiform film thickness. Therefore, the film must be ground, for adjusting the thickness, after being dried and baked.
  • the object of the present invention is to form a film of high quality on a part of the compressor to be formed with the film.
  • a film forming method for forming a film by attaching a fluid paint on a film forming area comprising the steps of attaching the fluid paint to the film forming area, and removing by centrifugal force the surplus portion of the fluid paint attached on the film forming area.
  • the method for removing the surplus portion of the paint by centrifugal force is effective for securing a uniform film thickness.
  • the paint is a resin containing a solid lubricant.
  • the resin containing a solid lubricant effectively forms a film for an improved slidability.
  • a film forming method comprising further the step of spreading said paint on the flat surface of the film forming area due to the centrifugal force.
  • a film forming method described in the aforementioned first or second aspect in which a film is formed on the film forming area of a part of the compressor to be formed with a film.
  • the film formed by removing the surplus portion of the paint by centrifugal force has a uniform thickness.
  • a film forming method for the compressor of swash plate type comprising a piston and a swash plate rotated integrally with the rotary shaft, wherein at least a shoe is interposed between the swash plate and the piston in such a manner as to be in sliding contact with both the swash plate and the piston, wherein the rotation of the swash plate is transmitted to the piston through the shoe thereby to reciprocate the piston, and wherein the part to be formed with a film is the swash plate and the area of the swash plate in sliding contact with the shoe constitutes the film forming area.
  • the area of the swash plate in sliding contact with the shoe preferably constitutes a film forming area by removing the surplus portion of the paint by centrifugal force.

  • the rotary shaft 13 is driven by an external drive source (such as a vehicle engine).
  • a rotary support member 14 is fixedly mounted on the rotary shaft 13, and a swash plate 15 is slidably and inclinably supported along the axis of the rotary shaft 13.
  • the swash plate 15 of iron material is formed integrally with a support member 151 on which a guide pin 16 is secured.
  • the guide pin 16 is slidably fitted in a guide hole 141 formed in the rotary support member 14.
  • the swash plate 15 is rotatable integrally with the rotary shaft 13 and inclinably along the axis of the rotary shaft 13 in collaboration between the guide hole 141 and the guide pin 16.

  • Each cylinder bore 111 contains a piston 17.
  • the upper piston 17 is located at the top dead center and the lower piston 17 at the bottom dead center.
  • the motion of the swash plate 15 rotated integrally with the rotary shaft 13 is transformed into the longitudinal reciprocal motion of the piston 17 through hemispherical shoes 18A, 18B, so that the piston 17 reciprocates longitudinally in the cylinder bore 111.
  • the shoe 18A of iron material is in sliding contact with one sliding contact surface 30 of the swash plate 15 and the shoe 18B of iron material is in sliding contact with the other sliding contact surface 31 of the swash plate 15.
  • the refrigerant in the suction chamber 191 flows into the cylinder bore 111 by forcibly pushing off a suction valve 211 on a valve forming plate 21 from a suction port 201 on the valve plate 20.
  • the refrigerant that has flowed into the cylinder bore 111 is discharged into a discharge chamber 192 by forcibly pushing off a discharge valve 221 on a valve forming plate 22 from a discharge port 202 on the valve plate 20.
  • the opening degree of the discharge valve 221 is controlled by contact with a retainer 231 on a retainer forming plate 23.

  • the shoe 18B in sliding contact with the other sliding contact surface 31 of the swash plate 15 is held unremovably on the recess 173.
  • the end surfaces 152, 153 making up the film forming area are formed with films 32, 33, respectively.
  • the surface of the film 32 constitutes the sliding contact surface 30, and the surface of the film 33 makes up the sliding contact surface 31.
  • the films 32, 33 are formed by use of a film forming unit shown in Fig. 2A.
  • the swash plate 15 is mounted on a rotary holding mechanism 34 rotated in the direction of arrow Q1 by a motor M.
  • a receptacle 35 is arranged around the rotary holding mechanism 34.
