Abrégé

An adjustable bladder assembly for use with a closed hydraulic power system is provided. The bladder assembly includes a rigid body and a bladder cover slidably engaged therein. The bladder cover divides an interior area of the bladder assembly into first and second portions. The first portion of the bladder assembly is configured to be in fluid communication with a fluid reservoir of the hydraulic power system, with internal pressure of the hydraulic power system acting on an inner surface of the bladder cover, thereby biasing the bladder assembly towards an inflated configuration. The second portion of the bladder assembly is open to the environment such that ambient air pressure acting on an outer surface of the bladder cover biases the bladder assembly towards a deflated configuration.

Abrégé

A rapid floor jack having an internal linkage is disclosed. The linkage comprises: a body (103), a lift arm (111) pivotally attached to the body (103) at a first pivot point and an actuator (107), a power arm (129) pivotally attached to the body (103) at a second pivot point. The power arm (129) is also pivotally connected to the actuator (107) at a third pivot point spaced at a first distance from the second pivot point. A connecting arm (141) has a proximate end pivotally attached to the power arm (129) and a distal end pivotally attached to the lift arm (111). The proximate end of the connecting arm (141) is preferably connected to the power arm (129) at a fourth pivot point which is spaced at a second distance from the second pivot point wherein the second distance is greater than the first distance, however the proximate end of the connecting arm (141) can alternatively be connected to the power arm (129) at the third pivot point. The floor jack having the linkage can lift the load faster and easier.
