Abstract
A linear solenoid valve apparatus includes a linear solenoid housed within a valve body. The linear solenoid valve includes a sleeve with an open channel conduit on its exterior surface, an exhaust port in communication with the open channel in the lower portion of the sleeve, a feedback port, a spool and a spring. The valve body includes a supply passage connecting with the open channel, off center at the top of the sleeve. The structure is designed to prevent the valve from sticking.
