Abstract
A linear solenoid-operated valve which includes a housing having a first and second ports opening into a bore, and a cylindrical spool formed with a through hole and axially slidable in the bore. A slot is formed at one end of the spool so as to define in combination with the first port a bypass passageway operable to a variable degree upon axial movement of the spool. A chamfer is formed on an intermediate surface of the spool in a direction toward the through hole. A restrictor having an orifice formed therein is provided at the one end of the spool. The spool is spring-biased in a direction to close the bypass passageway, and is shiftable by an energized solenoid to open the bypass passageway.
