This traps the gas in the space between the “screws” of their rotors. As the screws rotate, this trapped volume decreases which not only compresses the gas but moves it towards the exhaust. WebA ball screw works in a similar way to a conventional lead screw, but the significant advantage of using a ball screw is that it uses ball bearings running in the helical channel to transmit the load. In high precision applications it is often necessary to translate the rotary motion from a motor to linear motion for the payload. tru holiday express 75 new york
