Abstract
A solenoid operated spool valve has a dampening reservoir formed at one end of the spool and which is ported for immersion in a fluid sump. The reservoir port is oriented vertically above the spool and a cap with an offset port is received over the reservoir port to baffle fluid flow from the reservoir and prevent the reservoir from draining when the port is fluid starved in the sump.
