摘要： PURPOSE:To obtain a variable capacity type cam plate compressor positive in capacity control even during high speed operation and suppressed in vibration and abrasion by providing a member having a spherical part or a cylindrical face part and a plane part, between a rotary member and a plate member in such a way as to be brought into slidable contact with both members. CONSTITUTION:A recessed spherical part 141 is formed at a drive plate 14, and a shoe 16, formed into the shape of having a plane part at a part of a sphere of the same radius, is brought into contact with the spherical part 14 in such a way as to be rotatable around the sphere center of the spherical part 141. A plane part 121 provided at a cam plate 12 is brought into slidable contact with the plane part of the shoe 16. The surface pressure at the time of transmitting thrust direction compressive force acting upon a piston 11 is thereby made small so as to provide a variable capacity type cam plate compressor restrained from the generation of abrasion and seizure at this part.

摘要： PURPOSE:To reduce vibration and noise by providing the first supporting member for swivel angle-variably supporting a swivel member for swiveling a piston and the second supporting member for supporting, a rotary member tilt angle- variably in relation to a main shaft. CONSTITUTION:In a variable displacement compressor, by rotating a swash plate 12 through a drive plate 14 by rotating a main shaft 13, a piston 31 is reciprocated in a cylinder 33 through a connecting rod 32 whose one end is brought into slide contact with this swash plate 12 through a thrust bearing 25, and fluid is sucked from a suction port 401, compressed and delivered from a delivery port 402. Here a balance weight 36 is mounted to the swash plate 12 by guide pins 37.... While a balance weight tilt roll supporting pin 42 is fixed to a central part of the balance weight 36 with this pin 42 slidably restricted in the axial direction of the main shaft 13 for a sleeve 15. Thus, in all the swash plate tilt angles, vibration and noise, following unbalanced inertia force, are reduced.

摘要： PURPOSE: To make noise low and reduce the dispersion of a noise level by separating a motor flange from a brush part, and enfolding to seal a motor peripheral part by a motor case while securing a clearance for keeping a contactless state between the motor case and a motor excluding a motor flange connecting part. CONSTITUTION: A blower device is provided with a motor 2 and a motor case 5. A motor flange 6 has radial dimension smaller than the outer diameter dimension of a fan 1, and a motor peripheral part is extended in the same direction as the radial direction of the motor 2. A flange part 5a has an outer fitting part 5m with larger radial dimension than the outer diameter dimension of the fan 1, and an inner supporting part 5n with smaller radial dimension than the outer diameter dimension of the fan 1. A housing part 5b enfolds to seal the motor 2 while securing a clearance for keeping a contactless state between the inner peripheral part of the housing part 5b and the outer peripheral part of the motor 2 excluding the motor flange 6 part. The noise of the blower device is thereby reduced, and noise offensive to the ear is reduced.

摘要： PURPOSE:To reduce the transmission of vibrational force so as to suppress the generation of noise by dividing a motor case axially in two pieces, and clamp-fixing a motor into the divided case. CONSTITUTION:A motor case and a flange 5 are integrally formed of synthetic resin or compounded material. A first case 4a with a cylindrical part, and a second case 4b are connected at the flange part 5 by a connecting member such as a screw 7 so as to form the motor case axially divided into two pieces. An O-ring shaped elastic body 8 disposed between the end faces near the outer periphery of an end bracket 6b is clamp-fixed into the second case 4b. A motor 2 is thereby enclosed in the cylindrical part, with a small protrusion 4c as a guide, so that motor noise is shielded within the motor case 4a.

摘要： PURPOSE:To provide a variable capacity type compressor with less vibration and noise, excellent in capacity controllability and favourable in durability. CONSTITUTION:It is constituted of a support sleeve 25 to support a piston support 21 to drive a piston 31 and a cam plate 12 to oscillate the piston support 21 by way of varying the oscillation angle and a cam plate sleeve 15 to support the cam plate 12 by way of varying the inclination against a spindle 13. A centrifugal force to work on the spindle 13 is made to be zero, and it is constituted so that moment generated in company with rotation of the cam plate 12 comes to be larger than moment generated by inertia forces of reciprocal motions and oscillation motions of the piston 31, the piston support 21 and others.

摘要： PURPOSE:To make a thrust load zero and abolish a thrust bearing by making an oscillating member be in axial contact with a static member directly or through an intermediate member without a main shaft, and regulating a minimum volume position of a compressor. CONSTITUTION:When a main shaft 13 of a compressor is driven, a driving plate 14 and a swash plate 12 are rotated, and a piston support 21 is oscillated. A piston 31 is thus reciprocated in a cylinder, and a refrigerant is run into a suction port 301. In the case that a compressor capacity is varied from a maximum to minimum, a swash plate sleeve 15 is slid and a tilting angle of the swash plate 12 is gradually decreased. A support sleeve 25 engaged with the swash plate sleeve 15 through a roll bearing 29 is moved by means of a sliding pin 30 and a recession 251 of the support sleeve 25. An end 252 of the support sleeve 25 on the side of a cylinder head 4 is abutted against an end 202 of a bearing housing 201 of a cylinder block 2.
