摘要： An oil and vacuum pumps group (1) for a motor vehicle engine comprises a motion transmission shaft (30) extending along a main axis X-X, an oil pump (10) and a vacuum pump (20) fitted on the motion transmission shaft and a gear (40) also fitted on the motion transmission shaft and adapted to derive a rotary motion from a driving gear (41) of a motor vehicle engine and to transfer said rotary motion to the motion transmission shaft to drive the oil pump and the vacuum pump. Advantageously, the oil and vacuum pumps group of the invention is structurally independent from and adapted to be associated with said motor vehicle engine. Preferably, the oil pump (10) and the vacuum pump (20) are units which are structurally independent from each other and the gear (40) of the oil and vacuum pumps group is operatively placed between the oil pump and the vacuum pump.

摘要： The invention relates to a vacuum pump (1) for vehicle motors, comprising a stator (2) , a chamber defined within said stator (2) and at least one vane rotatably mounted inside said chamber so as to generate a depression. The stator (2) comprises inlet openings for air and oil, and a first discharge outlet (30) on which a first one-way valve operates (35) . According to the invention, the stator (2) further comprises a second discharge outlet (50) separate from said first discharge outlet (30) and a second one-way- valve (55) operating on said second discharge outlet (50) . In this manner it is possible to separate the air discharge from the oil discharge, both physically and operationally. The invention further relates to a one-way valve for said vacuum pump. Such" valve comprises a blade body (60) having a first blade which defines a first one-way valve (35) and at least one second blade which defines at least one second one-way valve (55) .
