摘要： A mobile lubrication unit (1) comprising at least one motor (2) driving at least one reciprocating positive displacement pump (3) is disclosed. The reciprocating positive displacement pump (3) comprises a lubrication inlet (4), a piston rod (5) acting on a piston (6), which is fitted inside a corresponding cylinder (7) so that a cylinder chamber (8) is established inside the cylinder (7) in front of the piston (6). The cylinder chamber (8) is also provided with a lubrication outlet (9). The mobile lubrication unit (1) is characterized in that the piston rod (5) and/or the piston (6) comprises at least one conduit (10) for establishing fluid communication between the lubrication inlet (4) and the cylinder chamber (8). Furthermore, a method for creating a high-pressure flow of lubrication is disclosed.

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.

摘要： The invention relates to a chain fluid pump (20) for a power chain saw (10), which chain fluid pump (20) takes up the chain fluid through a suction line (29) from a tank (22) and feeds it through a pressure line (27) to a saw device (12) of the power chain saw (10). To allow for the chain fluid pump to be switched off in a simple manner the invention provides for controllable means (23-26) for cutting off the chain fluid supply to the saw device (12) by means of which the pressure line (27) can be cut while the chain fluid pump (20) is running and the chain fluid supplied by the chain fluid pump (20) can simultaneously be fed back into the suction line (29).
