Abstract
A regulating valve includes a housing, a piston, a spring disk, an outer cover, a plunger, a first spring, and a second spring along a valve axis. The housing forms a valve inlet and a valve outlet. The piston is disposed within the housing at the valve inlet. The piston forms a first cavity. The spring disk is disposed within the piston and further forms the first cavity. The outer cover forms a second cavity axially between the outer cover and the spring disk. The plunger is disposed at the outer cover. The plunger extends along the valve axis between and to a first axial plunger end and a second axial plunger end. The first axial plunger end is disposed within the second cavity. The first spring extends axially between and contacts the spring disk and the piston. The second spring extends axially between and contacts the spring disk and the outer cover.
