发明名称 Lever arm pump
摘要 A pump is described including an elongated cylindrical reservoir, a valve casing, at which the pump is pivotally fixed in space, and a pump chamber which are in a linear arrangement. A piston within the pump chamber is connected to a link, the end of which is pivotally fixed in space. A handle atop the reservoir is used to pump fluid from the reservoir to an attached device to be operated. Bores and check valves within the valve casing regulate the flow of fluid through the pump. A release mechanism which allows fluid to flow from the attached device to be operated back into the reservoir is activated by rotating the handle.
