    • A multi-piston swash plate type compressor with an internal lubricating arrangement for an air-conditioning system used in a vehicle such as an automobile including a cylinder block body having a swash plate chamber formed therein receiving a swash plate, cylinder bores formed therein for receiving pistons, and a central axial bore formed therein for receiving a driving shaft, the driving shaft being rotatably supported in the axial bore by radial bearings provided therein and by thrust bearings provided around the shaft at the sides of the swash plate. The compressor has suction and discharge chambers communicated with the cylinder bores through reed valves. The swash plate chamber is fed with a refrigerant inclusive of a lubricating oil from the air-conditioning system, and the refrigerant is then fed to the suction chamber through the axial bore. The thrust bearings have a race element surrounding the shaft, a clearance between the race element and the shaft being locally widened for increasing a flow rate of the refrigerant to be introduced into the axial bore through the thrust bearings.
    • 一种多活塞斜盘式压缩机,其具有用于诸如汽车的车辆中使用的空调系统的内部润滑装置,所述汽车包括具有形成在其中的旋转斜盘室的气缸体,所述旋转斜盘室容纳旋转斜盘,形成在其中的气缸孔用于接收 活塞和其中形成的用于接收驱动轴的中心轴向孔,所述驱动轴通过设置在其中的径向轴承以及在所述旋转斜盘的侧面处设置在所述轴周围的推力轴承可旋转地支撑在所述轴向孔中。 压缩机具有通过簧片阀与气缸孔连通的抽吸和排出室。 旋转斜盘室从空气调节系统供给含有润滑油的制冷剂,然后通过轴向孔将制冷剂送入吸入室。 推力轴承具有围绕轴的座圈元件,座圈元件和轴之间的间隙被局部加宽,以增加通过推力轴承引入到轴向孔中的制冷剂的流量。

    • A piston type compressor having a cylinder block in which a plurality of compression chambers permit a plurality of pistons to be reciprocated so as to compress a refrigerant sucked from a suction chamber formed in an end housing into the compression chambers through suction ports of a valve plate openably closed by a plurality of suction reed valves. The compressor also has a valve stop construction for stopping the movement of the suction reed valves when the valves reach the opening position thereof apart from the valve plate. The valve stop construction includes recessed seats formed in an axial end face of the cylinder block so as to permit a portion of the free end of respective suction reed valves to be first seated on the recessed seats, and to permit the remaining portion of the free end of the suction reed valves to be stably seated on the recessed seats. The gradual stoppage of the suction reed valves suppresses vibration of the valves and prevents noise.
    • 一种具有气缸体的活塞式压缩机,其中多个压缩室允许多个活塞往复运动,以便通过阀板的吸入口将形成在端部壳体中的吸入室吸入的制冷剂压缩到压缩室中 可打开地由多个吸入簧片闭合。 压缩机还具有阀止动结构,用于当阀门到达其与阀板的开启位置时停止吸入簧片阀的运动。 阀门止动结构包括形成在气缸体的轴向端面上的凹座,以便允许相应的吸入簧片阀的自由端的一部分首先坐在凹座上,并允许剩余部分的自由 吸入簧片阀的端部能够稳定地安置在凹座上。 吸入簧片阀的逐渐停止抑制阀的振动并防止噪音。

    • The cylinder block assembly (1a) of a swash plate type refrigerant compressor is formed with a suction passageway (17) in which a refrigerant gas containing a mist-like lubricant oil therein is sucked and passed therethrough, and a cylindrical separating chamber (22) is formed by an extension (21) from an inner wall of the suction passageway and has an opening directed toward an entering direction of a flow of the lubricant oil-containing refrigerant gas. The separating chamber (22) is provided with an bottom wall (22a) having a through-hole for an entrance of the oil, communicating between the separating chamber (22) and a swash plate chamber (4). The refrigerant gas containing the lubricant oil therein enters the cylindrical separating chamber (22) arranged in the suction passageway (17) and impringes upon an inner wall (22b) and the bottom wall (22a), whereby the flow direction thereof is changed, and flows out of the chamber through the opening into the suction passageway to thereby separate the lubricant oil from the refrigerant gas. The separated lubricant oil is supplied from the separating chamber (22) into the swash plate chamber (4), without overflowing from the chamber toward the suction passageway.
