COMPACT CONTROL MECHANISM FOR AXIAL MOTION CONTROL VALVES IN HELICAL SCREW COMPRESSORS |
| 摘要 |
An axial slide valve is provided with an axially extending fluid chamber at each end with one chamber receiving a spring and being acted on by suction pressure and the other chamber coacting with a fixed piston and being acted upon by discharge pressure or the like whereby the slide valve is positioned so as to balance the spring and fluid pressures and thereby the compressor capacity.
