Abstract
An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.
Claims14
An apparatus, comprising:
- a valve member configured to be movably disposed within a valve pocket defined by a cylinder head of an engine, the cylinder head configured to be coupled to a gas manifold and a cylinder of the engine, the valve member defining a flow opening, the valve member configured to move relative to the cylinder head a distance along a longitudinal axis of the valve member between a closed position and an opened position, the flow opening in fluid communication with the cylinder of the engine when the cylinder head is coupled to the cylinder of the engine and the valve member is in the opened position, the flow opening in fluid communication with the gas manifold of the engine when the cylinder head is coupled to the gas manifold and the valve member is in the opened position or the closed position.
A method, comprising:
- moving a valve member, in a direction parallel to a longitudinal axis of the valve member, within a valve pocket defined by a cylinder head, the valve member having a portion defining a plurality of valve flow passages, the valve member configured to be reciprocated within the valve pocket by an actuator between a closed position and an opened position;
- and
- disposing a first portion of a biasing member into the valve pocket such that the first portion contacts an end portion of the valve member.
An apparatus, comprising:
- a cylinder head having an interior surface defining a valve pocket, the cylinder head configured to be coupled to a cylinder and a gas manifold;
- and
- a valve member defining a plurality of valve flow passages, the valve member 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 apparatus having a first configuration and a second configuration, in the first configuration each valve flow passage from the plurality of valve flow passages is in fluid communication with the cylinder and the gas manifold, in the second configuration, each valve flow passage from the plurality of valve flow passages is fluidically isolated from the cylinder.
