    • A piston (35) type compressor has a housing, a crank chamber (15) and a drive shaft (16) supported by the housing. A front restriction (11a) and a rear restriction (51a, 14e) are located in the housing. The front and rear restrictions (11a, 51a, 14e) restrict axial movement of the drive shaft (16). The front restriction (11a) restricts forward movement of the drive shaft (16). The rear restriction (51a, 14e) restricts rearward axial movement of the drive shaft (16). A first clearance (X1) is located between the rear end of the drive shaft (16) and the rear restriction (51a, 14e) when the drive shaft (16) is restricted by the front restriction (11a). A second clearance (X2) is formed between the piston (35) and a valve plate (14) when the drive shaft (16) is restricted by the front restriction (11a) and when the piston (35) is in the top dead center position. The first clearance (X1) is narrower than the second clearance. The method of assembly the piston (35) easily sets the first clearance (X1).
    • 活塞(35)型压缩机具有壳体,曲轴室(15)和由壳体支撑的驱动轴(16)。 前部限制部(11a)和后部限制部(51a,14e)位于壳体内。 前部和后部限制件(11a,51a,14e)限制驱动轴(16)的轴向移动。 前限制件(11a)限制驱动轴(16)的向前运动。 后限制件(51a,14e)限制驱动轴(16)的向后轴向移动。 当驱动轴(16)被前限制部(11a)限制时,第一间隙(X1)位于驱动轴(16)的后端与后限制部(51a,14e)之间。 当驱动轴(16)被前限位件(11a)限制时和活塞(35)位于上止点位置时,活塞(35)和阀板(14)之间形成第二间隙(X2) 位置。 第一间隙(X1)比第二间隙窄。 组装活塞(35)的方法容易地设定第一间隙(X1)。 <图像>
