To provide a pump device for lubricant which is downsized and reduced in cost due to a simplified decompression structure. A pump device S for lubricant comprising a pump main body 10 which is provided with a cylinder part 15 which suctions lubricant stored in a tank and discharges it from a discharge port 13 and a piston 30 and an actuator 40 which allows the piston 30 to move forward and backward, in which when lubricant is supplied to a lubrication pipeline W connected to the discharge port 13, the discharge port 13 is compressed, and when the supply of lubricant to the lubrication pipeline is stopped, the discharge port 13 is decompressed, wherein the piston 30 is allowed to move forward to the 1 st position P1 at which lubricant is discharged, move backward from the 1 st position to the 2 nd position P2 at which lubricant is suctioned and further move backward from the 2 nd position to the 3 rd position P3, and a decompression path 50 which is blocked when the piston is allowed to move between the 1 st position P1 and the 2 nd position P2, and is opened when the piston is moved backward to the 3 rd position is formed in the pump main body 10.

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.

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.

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).
摘要:
Die Erfindung betrifft eine Fördervorrichtung (1) zur Förderung eines fließfähigen Mediums, mit einem Förderantrieb (2), einer Pumpenvorrichtung (3) und einer Schöpfvorrichtung (4). Der Förderantrieb (2) ist an einem ersten Ende (6) eines Rohres (5) angeordnet, wobei die Pumpenvorrichtung (3) und die Schöpfvorrichtung (4) innerhalb des Rohres (5) angeordnet sind. Die Schöpfvorrichtung (4) weist ein Fußventil (8) auf, das an einem zweiten Ende (7) des Rohres (5) angeordnet ist, mittels welchem Fußventil (8) ein Einlass (9) für einen Zustrom von Medium in eine Kolbenkammer (10) regelbar ist. In der Kolbenkammer (10) ist ein Kolben (11) angeordnet, der die Kolbenkammer (10) in einen Zuströmbereich (12) und einen Abströmbereich (13) unterteilt, wobei der Zuströmbereich (12) und der Abströmbereich (13) über den Kolben (11) verbindbar oder verbunden sind, wobei der Kolben (11) über eine Kolbenstange (14) mittels des Förderantriebs (2) zwischen einer Einfahrstellung und einer Ausfahrstellung innerhalb der Kolbenkammer (10) bewegbar ist (Fig.1).
