Definitions

  • the present invention relates to a swash plate type compressor. More particularly, the present invention relates to a swash plate type compressor that has a swash plate, on which coatings are formed, and pairs of shoes. Each shoe is located between the swash plate and one of the pistons. The coatings are applied to the area of the swash plate that contacts the shoes. Each shoe has a substantially flat surface and a semi-spherical portion. Each substantially flat surface contacts the swash plate, which integrally rotates with a rotary shaft. Each semi-spherical portion is fitted to one of two concave recesses of the corresponding piston. The rotational force of the swash plate is transmitted to the pistons through the shoes to drive the pistons.
  • Japanese Examined Patent Publication No. 61-1636 and Japanese Unexamined Patent Publication No. 11-193780 disclose a swash plate type compressor that has pistons, which reciprocate in accordance with the rotation of a swash plate that integrally rotates with a rotary shaft.
  • a shoe is provided between the front peripheral portion of the swash plate and each piston and between the rear peripheral portion of the swash plate and each piston. The shoes transmit force from the swash plate to the pistons. The shoes slide along the rotating swash plate.
  • the shoes which are made of iron-based material, may wear out or seize. Therefore, it is necessary to improve the sliding performance of the swash plate with respect to the shoes.
  • each hemispheric shoe is arched outward.
  • the radius of curvature of the arched portions is very large.
  • a first chamfered portion and a second chamfered portion are formed near the periphery of each arched surface.
  • the inclination angle of the second chamfered portion which is radially inward of the first chamfered portion, is smaller than the inclination angle of the first chamfered portion.
  • the first and second chamfered portions draw lubricant from the peripheral portion of the swash plate, which enters between each shoe and the swash plate. This improves the sliding performance of the swash plate with respect to the shoes.
  • coating which has high sliding performance, is applied to the swash plate to further improve the sliding performance of the swash plate with respect to the shoes.
  • the coating is applied to the front and rear peripheral portions of the swash plate, which contact the shoes.
  • a filter is provided in a passage for refrigerant gas.
  • the filter is provided for filtering foreign particles such as grinding chips of parts or wear particles in the compressor and an external refrigerant circuit.
  • the filter only catches foreign particles that are more than certain size to avoid clogging of the filter.
  • the foreign particles that pass through the filter may be caught between the swash plate and the shoes. Therefore, in the compressor that has the coated swash plate, the coating may be damaged depending on the size of foreign particles caught between the swash plate and the shoes. When the coating is damaged, the sliding performance of the coating decreases.
  • the objective of the present invention is to prevent foreign particles from adversely affecting or decreasing the effectiveness of a coating.
  • the present invention provides a swash plate type compressor that has at least a pair of shoes between a swash plate and a piston. Motion of the swash plate is transmitted to the piston through the shoes. The piston reciprocates according to the transmitted motion. A coating is applied to each of two surfaces of the swash plate to contact the shoes, respectively. The surface of each coating is flat.
  • Each shoe includes a substantially flat surface and a semi-spherical portion. Each substantially flat surface contacts the swash plate. Each semi-spherical portion is fitted to the piston.
  • the substantially flat surface of each shoe includes a main chamfered portion. The main chamfered portion is provided near the periphery of the substantially flat surface.
  • the inclination angle ⁇ 1 of each main chamfered portion with respect to the corresponding coating is a predetermined angle or less.
  • Each coating contacts one of the substantially flat surfaces.
  • the maximum distance ⁇ between each main chamfered portion and the corresponding coating is equal to or less than the thickness D of the corresponding coating.

  • a rotary shaft 13 is supported by a front housing 12, which defines a control pressure chamber 121, and a cylinder block 11.
  • the rotary shaft 13 is driven by an external drive source such as an engine of a vehicle.
  • a rotor 14 is secured to the rotary shaft 13.

  • a support body 151 is integrally molded with the swash plate 15 and is made of iron-based material.
  • a pair of guide pins 16 (only one guide pin is shown in Fig. 1) are secured to the support body 151.
  • Each guide pin 16 is slidably fitted in a corresponding guide hole 141, which is formed in the rotor 14.
  • the guide holes 141 and the guide pins 16 cooperate with each other. This permits the swash plate 15 to tilt with respect to the axis of the rotary shaft 13 and to rotate integrally with the rotary shaft 13. The tilting motion of the swash plate 15 is guided by the guide holes 141, the guide pins 16, and the rotary shaft 13.
  • the inclination angle of the swash plate 15 is changed by controlling the pressure in the control pressure chamber 121.
  • the pressure in the control pressure chamber 121 increases, the inclination angle of the swash plate 15 decreases.
  • the pressure in the control pressure chamber 121 decreases, the inclination angle of the swash plate 15 increases.
  • Refrigerant in the control pressure chamber 121 flows to a suction chamber 191 in a rear housing 19 through a pressure release passage, which is not shown in the figures.

  • a displacement control valve 25 is provided on the pressure supply passage.
  • the displacement control valve 25 controls the flow rate of refrigerant supplied to the control pressure chamber 121 from the discharge chamber 192.

  • the displacement control valve 25 controls the inclination of the swash plate 15.
  • the swash plate 15 When the swash plate 15 contacts the rotor 14, the swash plate 15 is at the maximum inclination angle. When a snap ring 24 on the rotary shaft 13 contacts the swash plate 15, the swash plate 15 is at the minimum inclination angle.

  • Each shoe 18A, 18B is made of iron-based material.
  • each piston 17 reciprocates in the corresponding cylinder bore 111.
  • the rear shoe 18A slides along the contact surface 30 of the swash plate 15.
  • the front shoe 18B slides along the opposite contact surface 31 of the swash plate 15.
  • refrigerant in the suction chamber 191 flows into the associated cylinder bore 111 from the corresponding suction port 201 in a first valve plate 20 and causes a corresponding suction valve 211 on a second valve plate 21 to open.
  • refrigerant in the associated cylinder bore 111 is then discharged from a corresponding discharge port 202 on the first valve plate 20 to the discharge chamber 192 and causes a corresponding discharge valve 221 on a third valve plate 22 to open.
  • Retainers 231 are formed on a fourth valve plate 23 to limit the opening degree of the discharge valves 221.
  • the discharge chamber 192 and the suction chamber 191 are connected by an external refrigerant circuit 26.
  • Refrigerant in the discharge chamber 192 flows to the suction chamber 191 through the external refrigerant circuit 26, which includes a condenser 27, an expansion valve 28, an evaporator 29.
  • coatings 32, 33 are formed on a rear peripheral portion 152 and a front peripheral portion 153 of the swash plate 15, respectively.
