Abstract:
A hydraulic valve includes a main body, a valve body, a piston, a valve sleeve, a spool and a resilient energy storage member. The valve body and the piston are disposed within the main body. The valve body defines a first chamber, a second chamber, and a cylindrical passage connecting the first chamber and the second chamber. The valve sleeve is moveably disposed in the cylindrical passage. The spool is moveably disposed within the bore of the valve sleeve. The resilient energy storage member may be disposed between the valve sleeve and valve spool. The resilient energy storage member is compressed as pressure is induced in one of the first chamber or the second chamber such that the valve sleeve and the spool move relative to one another so that at least a portion of the shaped aperture is exposed to the first chamber or second chamber to allow a proportional amount of hydraulic fluid to flow between the first chamber and the second chamber.
