摘要： A hand operated pump for generating negative and positive air pressure. The pump includes a pump body having a pump cylinder and a piston mounted for reciprocation in the cylinder. A selector valve communicates with the cylinder and is moveable between a positive-pressure position and a negative-pressure position. The arrangement is such that operation of an actuator to move the piston through a power stroke when the selector valve is in its negative-pressure position causes the pump to generate negative pressure at an outlet of the pump, and operation of the actuator to move the piston through a power stroke when the selector valve is in its positive-pressure position causes the pump to generate positive pressure at the outlet of the pump. A method of operating such a pump is also disclosed.
摘要翻译：用于产生负气压和正气压的手动泵。该泵包括一泵体，该泵本体具有一泵体和一活塞，该活塞安装用于在气缸内往复运动。选择阀与气缸连通并且能够在正压位置和负压位置之间移动。该装置使得当选择阀处于其负压位置时致动器使活塞移动通过动力冲程的操作使得泵在泵的出口处产生负压，并且致动器的操作使当选择阀处于其正压位置时，通过动力行程的活塞使得泵在泵的出口处产生正压力。还公开了一种操作这种泵的方法。
