Abstract
According to an embodiment, a valve assembly is provided for use with a fluid system for controlling flow rate to a fluid circuit for cooling and/or lubricating a clutch assembly in a transmission. The spool valve has a first outlet and a second outlet in fluid communication with the fluid circuit. The spool valve has a first configuration with zero flow to the fluid circuit, a second configuration providing a first flow to the fluid circuit through the first outlet, and a third configuration providing a second flow to the fluid circuit through the first and second outlets. The first outlet has a metering orifice. The flow across the valve is a function of the stroke distance of the spool.
