Abstract

A lightweight hydraulic jack having a gray iron sleeve embedded within a cast aluminum housing, a steel plunger mounted for reciprocal motion within the sleeve, the sleeve being provided with an annular shoulder and a number of longitudinal ribs to prevent movement of the sleeve with respect to the housing. Hydraulic fluid is pumped from a reservoir in the housing into the sleeve and from the sleeve back to the reservoir through steel valve seats which are positioned at the control points in a fluid passage network in the housing.
