Abstract
An apparatus includes a cylinder head and a valve member. The cylinder head is configured to be coupled to a cylinder and a gas manifold and has an interior surface defining a valve pocket. The valve member is configured to be disposable within the valve pocket such that the valve member is movable within the valve pocket along a longitudinal axis of the valve member. The valve member has a tapered portion defining multiple valve flow passages. The apparatus has a first configuration and a second configuration. When the apparatus is in the first configuration, each valve flow passage is in fluid communication with the cylinder and the gas manifold. When the apparatus is in the second configuration, each valve flow passage from the plurality of valve flow passages is fluidically isolated from the cylinder.
