摘要： The invention relates to a lubricant pump unit (P) for lubricating the cylinders in precise time with the cycle in internal combustion engines (M) such as diesel engines. Said pump unit contains a working piston (22), which drives several metering pistons (25) that are allocated to lubricating point connections and can be driven back and forth in feed and return cycles by means of a working stroke that can be adjusted to meter the supply of lubricating oil, a magnetically actuated control valve (V) being provided in a control oil circuit of the working piston. The working piston (22) is subjected in turn to a hydraulic pressure both in the feed cycle and the return cycle by the control oil circuit.
