摘要： A piston cartridge having a piston chamber, an inlet port, an outlet port, and a piston moveable between a first position and a second position. Also, the cartridge includes a first barrier positioned between the piston and the inlet port and a first sealing member moveable between the first barrier and the inlet port, wherein the first sealing member seals the inlet port when positioned adjacent to the inlet port but allows the fluid into the chamber when positioned adjacent to the first barrier. In addition, the cartridge also includes a second barrier positioned adjacent to the outlet port and a second sealing member moveable between the piston and the second barrier, wherein the second sealing member seals the outlet port when positioned adjacent thereto but allows the fluid to pass through the outlet port when positioned adjacent to the second barrier.

摘要： A pump that includes a piston moveable along a first axis and an eccentric cam positioned about a second axis, wherein the second axis is substantially perpendicular to the first axis. The pump also includes an actuator positioned adjacent to the cam and configured to move the cam along the second axis. In addition, the pump further includes a cam-adjacent bearing positioned between the piston and the cam, wherein the cam-adjacent bearing remains positioned substantially along the first axis upon movement of the cam along the second axis.
摘要翻译：一种泵，包括可沿着第一轴线移动的活塞和围绕第二轴线定位的偏心凸轮，其中所述第二轴线基本上垂直于所述第一轴线。泵还包括邻近凸轮定位并被构造成沿着第二轴线移动凸轮的致动器。此外，泵还包括定位在活塞和凸轮之间的凸轮相邻轴承，其中当凸轮沿着第二轴线移动时，凸轮相邻轴承基本上沿第一轴线保持定位。

摘要： A method and apparatus is provided that includes a hand pump having a handle locking mechanism, a counter bored nut, pivoting links, and unloading valve assembly. The unloading valve assembly allows a pump operator to pump a larger volume of hydraulic fluid and/or to pump to higher pressures in first stage operation than a conventional pump which employs a direct-acting relief valve. The unloading valve also decreases the effort required to pump the handle during second stage operation. The handle locking mechanism allows the pump handle from moving during transporting and storing of the hand pump. The counter bored nut allows for more reservoir room than conventional hand pumps. The pivoting link allows for greater leverage of the handle during pumping.
