12 Diaphragm valve 13 Exhaust valve 14 Exhaust port Fig. 2 Operating principle of a TRIVAC NT 5 (other TRIVAC NT types operate in a similar way) Principle of Operation The rotor (2/6) which is eccentrically arranged in the pump housing (pump chamber) has two radially sliding vanes (2/7 and 2/9) which divide the pump chamber of the pump into several chambers. - Page 8 This and the combination with the large usable oil reservoir, results in long intervals between the oil exchanges, even at high intake pressures. The gas ballast valve (GB) is opened or closed by turning it (positions 0, 1, 2, 3). 17200918_001_A1 - 06/2008 - © Oerlikon Leybold Vacuum...
