摘要： A compressor has a drive plate (22) located in a crank chamber (15) and tiltably mounted on a drive shaft (16) and a piston (35) operably coupled to the drive plate (22) and located in a cylinder bore (11a). The inclination of the drive plate (22) is variable according to a difference between the pressure in the crank chamber (15) and the pressure in the cylinder bore (11a). The compressor has an adjusting mechanism for adjusting the pressure in one of the crank chamber (15) and a suction chamber (37) to vary the difference between the pressure in the crank chamber (15) and the pressure in the cylinder bore (11a). The adjusting mechanism includes a gas passage (48; 110) for passing the gas used for adjusting the pressure and a control valve (49) for adjusting the amount of the gas flowing in the gas passage (48; 110). The control valve (49) includes a valve body (67), a reacting member (73) and a solenoid (65). The valve body (67) adjusts the opening size of the gas passage (48; 110). The reacting member (73) moves the valve body (67) in accordance with the pressure of the gas supplied to the compressor from the external circuit (52). The solenoid (65) biases the valve body (67) in a direction with the force based on a value of current supplied to the solenoid (65). A supplying apparatus supplies undulating current to the solenoid (65). The supplying apparatus varies the average value of the undulating current to vary the biasing force of the solenoid (65).

摘要： An improved lubricating structure of a compressor is disclosed. A swash plate is tiltably supported on the drive shaft for an integral rotation therewith. A plurality of pistons are operably coupled to the swash plate. The rotation of the swash plate is converted to a reciprocal movement of each piston in an associated cylinder bore to compress and discharge gas that contains oil. A clearance is defined by the cylinder bore and the piston enabling the compressed gas to flow out from the cylinder bore to the swash plate. The swash plate has an operation area that receives greatest compression load based on reaction force of the compressed gas acting on the piston when the swash plate rotates. The swash plate has at least one bore for attaching the swash plate to a jig when the swash plate is ground during its manufacturing process. The bore is arranged to allow the gas flow out to the swash plate from the cylinder bore through the clearance to flow to the operation area.

摘要： L'invention concerne une soupape de commande de déplacement (49) améliorée intégrée dans un compresseur à déplacement variable. La soupape de commande (49) comporte un corps de soupape (54) et un solénoïde (52) permettant d'actionner le corps de soupape (54). La bobine (92) du solénoïde (52) est enroulée autour d'une armature de bobine réalisée en résine synthétique isolante. Une plaque de base fait saillie à partir de l'armature de bobine (92). Une paire de plaques conductrices est fixée sur la plaque de base. Chaque plaque présente un bloc de serrage. La bobine présente une paire de fils terminaux. Chaque fil terminal est fixé sur et connecté électriquement à l'un des blocs de serrage. Chaque fil terminal est enroulé autour d'un support formé dans chaque plaque entre l'armature de bobine et le bloc de serrage correspondant. Une diode est fixée sur les supports et est connectée en parallèle à la bobine. Une paire de bornes de la diode est fixée sur les supports correspondants par brasage et sertissage. Les supports empêchent la tension existant dans les fils terminaux d'être appliquée aux jonctions électriques formées entre les fils et les blocs de serrage, ce qui rend la soupape plus fiable.

摘要： An improved displacement control valve incorporated in a variable displacement compressor. The control valve includes a valve body and a solenoid for actuating the valve body. The coil of the solenoid is wound about a bobbin made of insulating synthetic resin. A base plate integrally protrudes from the bobbin. A pair of conducting plates are secured to the base plate. Each plate has a clamping block. The coil has a pair of terminal wires. Each terminal wire is secured to and electrically corrected to one of the clamping blocks. Each terminal wire is wound about a holder formed in each plate between the bobbin and the corresponding clamping block. A diode is secured to the holders and is connected in parallel with the coil. A pair of terminals of the diode are secured to the corresponding holders by soldering and crimping. The holders prevent tension in the terminal wires from being applied to electrical joints formed between the wires and the clamping blocks, which makes the valve more reliable.

摘要： A control valve in a compressor that adjusts the discharge displacement based on controlling of an inclination of a cam plate. The compressor includes a supply passage for connecting a discharge chamber with a crank chamber. The control valve is placed midway on the supply passage for adjusting the amount of the gas introduced into the crank chamber from the discharge chamber. The control valve has a valve hole and a valve chamber respectively disposed midway on the supply passage. A valve body is located in the valve chamber to adjust the opening size of the valve hole. A reacting member reacts to the pressure in the first area. The reacting member moves the valve body via a first rod in accordance with the pressure in the first area. A solenoid is opposed to the reacting member with respect to the valve body. The solenoid has a fixed core, a plunger and a plunger chamber. Electric current sent to the solenoid produces a magnetic attractive force between the core and the plunger in accordance with a magnitude of the current. A second rod is placed between the plunger and the valve body to urge the valve body by the magnetic attractive force. The discharge chamber is connected with the valve chamber. The crank chamber is connected with the valve hole and the plunger chamber.

The inclination of the swash plate is varied according to the difference between the pressure in the crank chamber and the pressure in the cylinder bore. The compressor has a supply passage for connecting a discharge chamber with the crank chamber. A control valve is located in the supply passage for adjusting the amount of the gas introduced into the crank chamber from the discharge chamber through the supply passage. The control valve includes a valve body and a solenoid selectively excited and de-excited based on a supply of electric current from a driver to actuate the valve body. The solenoid generates a counter-electromotive force based on the self-inductance of the solenoid when the solenoid is de-excited. A protector, such as a diode, is connected in parallel with the solenoid. The protector passes the current based on the counter-electromotive force therethrough to prevent the current based on the counter-electromotive force from being supplied to the driver.

摘要： The lubrication structure is formed on the surface of the inclined drive plate (23) , and is formed of a number of passages (234,236, 237, 238,239) that compress and guide the gas carrying the lubricating oil onto the part of the drive plate under the greatest loading. A bearing (38) is interposed between the edge of the plate and the piston (37) that compresses the gas carrying the lubricant. A pair of guide pins (26,27) couple the drive plate to a second plate (224) fitted on the drive shaft to couple drive from the shaft. A counterweight (235) balances the passages formed on the face of the inclined drive plate.
