Abstract
A generator includes a rotor to be driven to rotate and generate electricity and a housing receiving the rotor. An oil supply includes an oil inlet port and an oil outlet port. A pressure regulating valve regulates the flow of oil from the inlet port to the outlet port. The pressure regulating valve includes a valve sleeve mounted within the housing. The valve sleeve extends into a bore within the housing. A valve spool is mounted within the valve sleeve. The valve sleeve has a flange abutting an outer face of the housing. Bolts tighten the flange against the housing. An inner end of the valve sleeve extends radially inwardly to form a ledge. The ledge is spaced away from an inner face of the housing. A valve sleeve, a sense piston and a valve spool are also disclosed and claimed.
