    摘要: The present invention relates to a pump assembly for pumping a fluid lubricant such as grease or oil, the pump assembly comprising: a pump mechanism (120) configured for moving a fluid lubricant; a pneumatic cylinder configured for being powered by an air source, the pneumatic cylinder (160) comprising a movable member (130) for operating the pump mechanism (120), wherein the pump assembly further comprising a switch (140) for detecting a position of the movable member (130); a valve (150) configured for shifting a position of the moveable member (130) upon an activation of the valve (150); and a control unit (1 10) operable connected to the switch (140) and the valve (150), whereby the control unit (1 10) is configured for controlling the activation of the valve (150) in response to a detection of the position of the movable member (130) by the switch (140), such that a pumping effect of the pump mechanism (120) can be controlled. Moreover, the invention relates to a lubrication system including a pump assembly (100).

    摘要: A poppet assembly includes a poppet housing (41) having an axis and first and second sets of housing ports (41a, 41b), which are axially spaced. A poppet seat (44) is provided in the housing, the seat having a set of seat ports (44a), and a poppet (43) is also located in the housing and is retained by the seat. The poppet has a set of poppet ports (43a), is biased against the seat in a first position and can be moved to a second position away from the seat. A poppet actuator (45), which is located in the seat, partially surrounds the poppet and is biased away from the poppet. When the poppet is in its first position, the first set of housing ports (41b) are in fluid communication with the second set of housing ports (41a) through the poppet ports (43a), and when it is in its second position, the first set of housing ports (41b) are in fluid communication with the seat ports (44a).

    摘要: A fluid pressure operated piston engine apparatus generally includes a piston unit, a valve configured to selectively direct pressurized fluid into the piston unit, a valve shifting mechanism, and a magnetic detent device. The magnetic detent device includes a valve actuating member coupled to a valve element in the valve. The valve actuating member is movable between first and second magnetically held positions respectively holding the valve element in first and second positions. The valve shifting mechanism includes a biasing device operatively connected to a shaft associated with the piston unit. As the shaft approaches the first and second ends of its stroke, the biasing forces are used at least partially overcome magnetic attraction holding the valve actuating member. In this manner, the valve actuating member moves between first and second magnetically held positions to cause the valve element to shift and redirect pressurized fluid into the piston chamber of the piston unit to effect reversal of the direction of travel of the shaft.

    摘要: A valve for controlling the pumping of an emulsion in the mixing of a liquid explosive which includes a piston which is controlled during reciprocation by two valve members which are biased by a spring so that it is not possible for both valve members to be displaced from their respective valve seats simultaneously. This results in precisely controlled pumping strokes.

    摘要: A piston pump which includes a seal formed by a valve member inside a cylinder with an end zone through which extends a fluid entry port, and wherein a piston rod is movable in a forward direction into a recess in the valve member, thereby to apply fluid pressure and then mechanical pressure to the valve member to displace the valve member into sealing engagement with end zone, and in a reverse direction to reduce pressure inside the recess thereby to unseat the valve member from the zone.
