    摘要： A single-headed piston type swash-plate compressor has a cylinder block having cylinder bores in which a plurality of pistons are slidably received. A first housing is attached to a first end of the block to form a crank chamber therebetween, and a second housing is attached to a second end thereof to form an annular suction chamber and a central discharge chamber therebetween. The chambers are partitioned by an annular wall portion projected from an inner wall of the second housing such that the suction chamber surrounds the discharge chamber. A drive shaft rotatably is extended through the crank chamber, and a conversion mechanism is provided on the shaft for converting a rotating movement of the shaft into a reciprocating movement of each piston in the corresponding bore such that a suction stroke and a discharge stroke are alternately executed therein. During the suction stroke, a fluid is introduced from the suction chamber into the bore, and during the compression stroke, the introduced fluid is compressed and discharged from the bore into the discharge chamber. The cylinder block has a portion extended radially and outwardly from a side thereof, and the portion has a damping chamber formed therein. The discharge chamber has an elongated portion extended radially and outwardly therefrom, the elongated portion being in communication with the damping chamber through a small passage formed in the extended portion of the block.

    摘要翻译： 单头活塞式斜盘压缩机具有气缸体，其具有可滑动地容纳多个活塞的气缸孔。 第一壳体附接到块的第一端部以在其间形成曲柄室，并且第二壳体附接到其第二端，以在其间形成环形抽吸室和中心排出室。 这些室由从第二壳体的内壁突出的环形壁部分分隔开，使得吸入室围绕放电室。 驱动轴可旋转地延伸穿过曲柄室，并且在轴上设置转换机构，用于将轴的旋转运动转换成相应孔中的每个活塞的往复运动，使得吸入冲程和排出冲程交替 在其中执行。 在吸入行程期间，流体从吸入室引入孔中，并且在压缩行程期间，引入的流体被压缩并从孔排出到排放室中。 气缸体具有从其侧面径向向外延伸的部分，并且该部分在其中形成有阻尼室。 放电室具有从其向外径向延伸的细长部分，细长部分通过形成在块的延伸部分中的小通道与阻尼室连通。

    摘要： A compressor has a piston (11) that reciprocates between a top dead center and a bottom dead center in a cylinder bore (2a) by means of a driving body (9) mounted on a rotary shaft (6) in a crank chamber (5) during the rotation of the rotary shaft (6). The piston (11) has an outer circumferential surface that slides against an inner circumferential surface of the cylinder bore (2a). The outer circumferential surface of the piston (11) is provided with a groove (17; 44; 46) extending in the direction of an axis (S) of the piston (11). During reciprocation of the piston (11), lubricating oil adhered to the inner circumferential surface of the cylinder bore (2a) is collected in the groove (17; 44; 46). When the groove (17; 44; 46) is exposed to the inside of the crank chamber (5) from the cylinder bore (2a) during the reciprocation of the piston (11), the lubricating oil in the groove (17; 44; 46) is supplied to the inside of the crank chamber (5). The lubricating oil lubricates the driving body (9) and other parts in the crank chamber (5).
