摘要： Piston compressor for compressing gas, comprising a frame with at least one cylinder which has an essentially horizontal axis, a piston which is reciprocable in the cylinder, a piston rod which at one end thereof is fixed to the piston, while the other end thereof is coupled to a crosshead which is guided in the frame and is reciprocable by a drive mechanism, and bearing means which support the piston/piston rod unit, formed by the piston and the piston rod connected thereto, relative to the frame. The bearing means comprise: a source which continuously delivers a gas under pressure, conduit means which are connected to the source and open out at at least one outflow opening for supplying the gas coming from the source to a position between the piston and the cylinder, the postion of the at least one outflow opening and the pressure of the gas supplied from the source being such that gas supplied to a position between the piston and the cylinder constantly exerts an upward pressure on the piston/piston rod unit.
摘要翻译：一种用于压缩气体的活塞压缩机，包括具有至少一个具有基本水平轴线的气缸的框架，可在气缸中往复运动的活塞，其一端固定在活塞上的活塞杆，而另一端为联接到在框架中被引导并且可由驱动机构往复运动的十字头，以及支撑由相对于框架连接到其上的活塞和活塞杆形成的活塞/活塞杆单元的支承装置。轴承装置包括：连续输送压力气体的管道装置，其连接到源并在至少一个流出开口处开口，用于将来自源的气体供给到活塞和气缸之间的位置，至少一个流出口的位置和从源供应的气体的压力使得供应到活塞和气缸之间的气体在活塞/活塞杆单元上不断地向上施加压力。

摘要： A rotary screw compressor comprising a casing (1), a male rotor (6) and a female rotor (18) enclosed in a working space. The casing has a discharge outlet (2) at the high pressure end and a suction inlet (3) at the low pressure end of the working space. At least one rotor is rotatably supported at the low pressure end through a bearing arrangement comprising a bearing bracket (11) fixed to an end cover (5). The bearing bracket has a cylindrical outer circumferential surface and projects into a cavity provided in the rotor forming a first chamber (9) between the bracket and the rotor. The bracket is provided with an oil feed channel to feed oil into the first chamber. The circumferential surface of the bearing bracket is provided with at least a groove connected to the oil feed channel and a recess (13) connected to an oil drainage channel (12) provided in the bearing bracket. Sealing means (8) are provided between the first chamber and the working space.
摘要翻译：一种旋转螺杆式压缩机，其包括封闭在工作空间中的壳体（1），阳转子（6）和阴转子（18）。壳体在高压端具有排出口（2）和在工作空间的低压端的吸入口（3）。至少一个转子通过包括固定到端盖（5）的轴承座（11）的轴承装置在低压端处可转动地支撑。轴承托架具有圆柱形的外圆周表面并且突出到设置在转子中的空腔中，形成在支架和转子之间的第一腔室（9）。支架设有供油通道，用于将油送入第一室。轴承座的圆周表面设置有至少一个连接到供油通道的槽和连接到设置在轴承座中的排油通道（12）的凹槽（13）。密封装置（8）设置在第一室和工作空间之间。
