摘要： A slide for use in a single screw compressor is disclosed. The screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of the slide instead of to the discharge port. The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the disclosed slide further allows the use of an offset discharge port in the casing, in relation to the main rotor.

摘要： A single screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of a slide instead of to the discharge port. The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the slide further allows the use of an offset •′ discharge port in the casing, in relation to the main rotor. This means that pressure acting through the discharge port in use of the compressor tends to press the slide against another structure than the main rotor, for instance a bearing housing, giving better support to the slide. The slide also provides an improved oil delivery arrangement.
摘要翻译：单螺杆压缩机布置成一直排放其主转子的凹槽，而不必在主转子壳体的排出口中设置止回阀。套管中的另外的出口将排气口的气体排入滑块的主体而不是排出口。排出的气体被引导到滑动件的出口，在压缩机的使用期间以及在所有的加载条件下，它们可以从其到达壳体的排出口或旁通端口。滑块的设计进一步允许使用相对于主转子的壳体中的偏移排出口。这意味着在使用压缩机时通过排出口作用的压力往往会使滑动件抵抗比主转子（例如轴承壳体）更多的结构，从而为滑块提供更好的支撑。滑块还提供了改进的输油装置。

摘要： A valve comprises a housing (1) having an inlet (4) and an outlet (5), and a pressure sensing port (8). A piston (6) slides in a part (3) of the housing (1) in response to a difference between a first fluid pressure at the pressure sensing port on the one side of the piston, and a second fluid pressure at the inlet and/or outlet on the other side of the piston (6). A valve member (7) carried by the piston is operable thereby to close the inlet (4) when said second fluid pressure is less than a value sufficiently greater than said first fluid pressure. The valve member (7) is movable with respect to the piston (6) to facilitate closing of the inlet (4), in response to a fluid flow from the housing (1) to the inlet (4), when the piston is not acting to close the inlet.
