摘要： 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.

摘要： A lubricator pump adjuster for use with a lubricator pump having a piston housed in a pump body and a rocker connected to the piston. The lubricator pump adjuster comprises a mounting fitting attachable to the pump body and a housing disposed on the mounting fitting. An actuator is disposed in the housing and connectable to the rocker, whereby activation of the actuator causes the rocker to move, thereby adjusting the stroke of the piston. The actuator is a rotary actuator with an output shaft. The lubricator pump adjuster includes a cam faced member attached to the output shaft, and a plunger in contact with the cam faced member that is connectable to the rocker. The cam faced member may include a spiral-ramped surface.

摘要： The high pressure lubricant pump (1) for steelworks comprises a body (2) provided with at least one cylinder (5) provided with a lubricant intake port (7) and a lubricant delivery port (8). Within the cylinder (5) a piston (10) is movable to pressurize the lubricant. The cylinder (5) and the piston (10) define a preassembled pumping unit (14) removably fixed into a seat (16) of the body (2).

摘要： In various embodiments, the invention provides a lubricator comprising a housing defining a main lubricant chamber adapted to contain a fluid lubricant. A piston pump in fluid communication with the main lubricant chamber may be adapted to be driven to discharge the lubricant from a pump chamber through a lubricant outlet in the housing. A check valve may be mounted on the lubricant outlet, to check the discharge of lubricant from the lubricator. The lubricator may include a motor having a drive shaft adapted to rotate a swash plate to act as a cam to drive reciprocating motion of the pump piston in the pump chamber. The drive shaft may be in axial alignment with the piston, the swash plate being set obliquely on the drive shaft to revolve when the motor is activated to give reciprocating motion to the piston in a direction parallel to the drive shaft. The piston may be biased in the pump chamber against the swash plate, so that the swash plate rides on the piston.

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).
