摘要： A swash plate type variable displacement compressor comprises cylinder bores, pistons, a suction chamber and a discharge chamber. A suction valve introduces a low pressure gas into a working chamber in each cylinder bore. A discharge valve introduces a high pressure gas in the working chamber into the discharge chamber during a compression stroke. A crank chamber communicates to each of the cylinder bores at rear sides of the pistons. A swash plate is tiltably supported on a drive shaft and connected to each of the pistons through associated rods. The swash plate makes the pistons reciprocate in response to its undulating swing motion and varies its inclination angle based upon pressure differential between pressure in the suction chamber and pressure in the crank chamber therefore adjusting discharge displacement. A gas supply passage communicates each cylinder bore to the crank chamber in order to supply gas having a lower pressure than that in the working chamber at the time of completing the compression stroke. A gas bleed passage communicates the crank chamber to the suction chamber in order to introduce gas in the crank chamber into the suction chamber. A pressure control valve is provided in the gas supply passage or the gas bleed passage to control pressure of gas in the crank chamber. A valve is provided for opening and closing the gas supply passage in the middle of the compression stroke of each of the pistons.
摘要翻译：斜盘式可变排量压缩机包括气缸孔，活塞，吸入室和排放室。吸入阀将低压气体引入每个气缸孔中的工作室中。在压缩冲程期间，排出阀将工作室中的高压气体引入排放室。曲柄室与活塞后侧的每个气缸孔连通。旋转斜盘可倾斜地支撑在驱动轴上，并通过相关的杆连接到每个活塞。旋转斜盘使得活塞响应其起伏的摆动运动往复运动，并且基于吸入室中的压力与曲轴室中的压力之间的压力差来改变其倾斜角度，因此调节排放位移。气体供给通道将每个气缸孔连通到曲轴室，以在完成压缩冲程时提供压力低于工作室中的压力的气体。排气通道将曲柄室连通到吸入室，以便将曲柄室中的气体引入吸入室。在气体供给通道或排气通道中设置压力控制阀，以控制曲柄室内的气体压力。设置有用于在每个活塞的压缩行程中间打开和关闭气体供给通道的阀。

摘要： A variable displacement compressor includes a rotor, which is fixed to a drive shaft, and a pivotal swash plate, which is supported on the drive shaft and slides in an axial direction along the drive shaft. A hinge mechanism is located between the rotor and the swash plate. The hinge mechanism rotates the swash plate integrally with the rotor and guides the pivoting and the sliding motion of the swash plate. The hinge mechanism includes a swing arm, which extends from the swash plate. The swash plate is made of aluminum or aluminum alloy material. The swing arm is separate from the swash plate and is made of iron-based metal material. Therefore, while the swash plate is light, the hinge mechanism is strong.

摘要： A piston type compressor has a housing, a crank chamber and a drive shaft supported by the housing. A front restriction and a rear restriction are located in the housing. The front and rear restrictions restrict axial movement of the drive shaft. The front restriction restricts forward movement of the drive shaft. The rear restriction restricts rearward axial movement of the drive shaft. A first clearance is located between the rear end of the drive shaft and the rear restriction when the drive shaft is restricted by the front restriction. A second clearance is formed between the piston and a valve plate when the drive shaft is restricted by the front restriction and when the piston is in the top dead center position. The first clearance is narrower than the second clearance. The method of assembly the piston easily sets the first clearance.

摘要： A control valve is used in connection with a variable displacement compressor that varies the discharge capacity by controlling an inclination of a cam plate located in a crank chamber. The inclination of the cam plate is variable based on crank chamber pressure caused by refrigerant in the crank chamber. Monitor pressure is monitored at a predetermined point in a refrigerant circuit for causing a change in the crank chamber pressure and ultimately varying the discharge capacity. The control valve has a housing, an internal control valve mechanism and an external control valve mechanism. The internal control valve mechanism is located inside the valve housing and has a first valve body and a first reacting member. The first reacting member is connected to the first valve body for reacting to the monitor pressure to cause a change in the crank chamber pressure. The external control valve mechanism is located inside the valve housing and has a second valve body and a second reacting member. The second reacting member is for reacting to an external signal to cause the second valve body to change in the crank chamber pressure. The internal control valve mechanism and the external control valve mechanism operate independently with each other.

摘要： A compressor has a front housing, cylinder block and a rear housing. The housings and cylinder block are secured to one another by a plurality of bolts. A plurality of pistons reciprocally move in cylinder bores to compress gas. Each of said bolts has a shaft extending through the housings and the cylinder block. A cam plate is supported on a drive shaft for integral rotation therewith to convert the rotation of the drive shaft to reciprocal movement of a piston in the cylinder bore. The piston rotates about its axis in accordance with rotation force transmitted from the cam plate and abuts against the shaft of the bolt, which extends in close proximity to the piston. The rotating piston abuts against the shaft so that the rotation thereof is restricted. The shaft has a diameter greater than that of a threaded portion formed at an end of the bolt. Since the threaded portion is smaller, the threaded portion does no damage to the piston during assembly.

摘要： An axial multi-piston compressor includes a drive shaft, a cylinder block having cylinder bores formed therein and surrounding the drive shaft, and a plurality of pistons slidably received in the respective cylinder bores, wherein the pistons are successively reciprocated in the cylinder bores by a rotation of the drive shaft so that a suction stroke and a discharge stroke are alternately executed in each of the cylinder bores. During the suction stroke, a fluid is introduced into the cylinder bore, and during the compression stroke, the introduced fluid is compressed and discharged from the cylinder bore such that a residual part of the compressed fluid is inevitably left in the cylinder bore when the compression stroke is finished. The compressor further includes a rotary valve for allowing the residual part of the compressed fluid to escape from the cylinder bore into another cylinder bore governed by the compression stroke.
