摘要： An apparatus for generating high hydraulic pressure with reduced pulsations, comprising a valve case attached to a motor main body and having a plurality of pneumatic cylinder units arranged therearound, a rotary valve rotatably fitted in the valve case, links each having one end pivoted to the piston of each pneumatic cylinder unit and the other end connected to an eccentric shaft portion provided on a crank shaft or the rotary valve, and hydraulic bases connected directly to the pneumatic cylinder units individually, the hydraulic pressure fluid being caused to flow-out from the hydraulic bases in succession by the rotation of the rotary valve, in such a manner that when the outflow of the fluid from one of the hydraulic bases is about to cease, the fluid starts to flow out from another hydraulic base, and when the flows of hydraulic fluid from the two hydraulic bases combine, the pulsation of the flow from one base is offset by that of the other single flow, making it possible for the hydraulic fluid to uniformly flow out without pulsation.

摘要： An automatic oil pump that includes a drive chamber having a reciprocal driving device and an oil chamber having a sucking device, located on two sides of a main body. The reciprocal driving device has a piston unit having a valve chamber at its center and a balance valve, pushed by a spring. The drive chamber has grooves on its inside wall. The piston unit has two channels, allowing air to flow into the valve chamber, passing two sides of the piston unit. On the piston unit is a driving rod, the driving rod penetrates into the main body and reaches into the oil chamber. A hermetic cover and a movable piston are attached to an end of the driving rod. On the wall of the piston unit are pluralities of through holes. The reciprocal driving device drives the piston in the oil chamber to move reciprocally, so oil is sucked into and out of the oil chamber continuously. Thereby, oil sucking speed and volume are upgraded to save time and labor, and oil pumping efficiency is enhanced.
