Abstract

The present invention is a hydraulic pump having a body having one or more cylinders, and at least one collapsible link, selectively actuatable into a first position and a second position. The at least one collapsible iink is located in the one or more cylinders. The pump also has at least one cam operably associated with the body,. and with the collapsible link. As the cam rotates, the cam will cause the collapsible link to slidably move within the cylinders when the collapsible link is in the first position, and when the collapsible link is in the second position,; a portion of the collapsible link is collapsed by engagement with the cam.
