Abstract
A method includes coupling a cylinder head to a cylinder block. A valve member is then moved into a valve pocket defined by the cylinder head such that a first stem portion of the valve member engages an actuator. A first portion of the biasing member is then disposed against a second stem portion of the valve member, the second stem portion being opposite the first stem portion. An end plate is then coupled to the cylinder head such that a second portion of the biasing member engages the end plate.
Claims20
An apparatus, comprising:
- a cylinder head configured to be coupled to a cylinder and a gas manifold, the cylinder head having an interior surface defining a tapered valve pocket, the cylinder head defining a plurality of cylinder flow passages configured to be in fluid communication with the cylinder, the interior surface of the cylinder head including a plurality of sealing portions, each sealing portion from the plurality of sealing portions corresponding to at least one cylinder flow passage from the plurality of cylinder flow passages,
- the tapered valve pocket configured to receive a valve member defining a plurality of valve flow passages, each sealing portion from the plurality of sealing portions configured to contact the valve member such that each valve flow passage from the plurality of valve flow passages is fluidically isolated from the corresponding cylinder flow passage from the plurality of cylinder flow passages.
An apparatus, comprising:
- a cylinder head having a side wall that includes a first surface defining a portion of a tapered valve pocket and a second surface defining a portion of a combustion chamber, the side wall of the cylinder head defining a plurality of cylinder flow passages configured to fluidically couple the combustion chamber to the tapered valve pocket, the first surface including a plurality of sealing portions, each sealing portion from the plurality of sealing portions corresponding to at least one cylinder flow passage from the plurality of cylinder flow passages,
- the tapered valve pocket configured to receive a valve member defining a plurality of valve flow passages, a sealing portion from the plurality of sealing portions that corresponds to a cylinder flow passage from the plurality of cylinder flow passages configured to fluidically isolate the cylinder flow passage from a corresponding valve flow passage from the plurality of valve flow passages when the valve member is in a closed position.
An apparatus, comprising:
- a cylinder head configured to be coupled to a cylinder and a gas manifold, the cylinder head defining a longitudinal axis and having an interior surface defining a valve pocket, a cross-sectional shape of the valve pocket within a plane substantially normal to the longitudinal axis being noncircular, the cylinder head defining a plurality of cylinder flow passages configured to be in fluid communication with the cylinder and with the valve pocket,
- the valve pocket configured to reciprocatably receive a valve member defining a plurality of valve flow passages such that the valve pocket substantially surrounds at least a portion of the valve member, the valve pocket configured to receive the valve member such that each valve flow passage from the plurality of valve flow passages is fluidically isolated from the corresponding cylinder flow passage from the plurality of cylinder flow passages when the valve member is in a closed position within the valve pocket.
