ENGINE VALVE ASSEMBLY INCLUDING DETENT MECHANISM CONFIGURED TO INCREASE FORCE BIASING VALVE TOWARD CLOSED POSITION WHEN VALVE IS AT OR NEAR CLOSED POSITION

A valve assembly includes a valve body defining a bore therein, a valve stem, a spring retainer, a valve spring, and a detent mechanism. The valve stem extends through the bore in the valve body and is adjustable between an open position and a closed position. The spring retainer is spaced apart fro...

More Information
Summary:A valve assembly includes a valve body defining a bore therein, a valve stem, a spring retainer, a valve spring, and a detent mechanism. The valve stem extends through the bore in the valve body and is adjustable between an open position and a closed position. The spring retainer is spaced apart from the valve body along a longitudinal axis of the valve stem and fixed relative to the valve body. The spring retainer defines a bore through which the valve stem extends. The valve spring is captured between the valve body and the spring retainer and is configured to apply a biasing force to the valve stem that biases the valve stem toward the closed position. The detent mechanism is configured to increase the biasing force applied to the valve stem when the valve stem is in the closed position or within a predetermined distance of the closed position.
