VAKUUMPUMPE MIT ÖLABSCHEIDER
摘要:
A vacuum pump (1) has an oil separator (42) connected downstream of its outlet (33) and a duct (45, 46) through which the oil separated in the oil separator (42) is returned to the vacuum pump (1). To feed back the oil in a simple manner, the oil feedback duct (45, 46) opens into a duct (47) that supplies gas ballast to the pump (1).
