Valve Assembly
First Claim
1. A valve assembly comprising:
- a valve attached to a cylinder head in a movable manner along its axial line direction so as to selectively fluidly connect or close between a combustion chamber and a gas line;
a plate-like holding member provided at the valve in a relatively immovable manner along the axial line direction; and
a coil spring externally inserted around the valve in a state where its proximal end is directly or indirectly engaged to an external surface of the cylinder head, the coil spring being configured so that its distal end has a diameter smaller than that of the proximal end, whereinthe holding member has an engaging surface facing one side along the axial line direction to hold the distal end of the coil spring.

Abstract
There is provided a valve assembly including: a valve attached to a cylinder head in a movable manner along its axial line direction so as to selectively fluidly connect or close between a combustion chamber and a gas line; a plate-like holding member provided at the valve in a relatively immovable manner along the axial line direction; and a coil spring externally inserted around the valve in a state where its proximal end is directly or indirectly engaged to an external surface of the cylinder head, the coil spring being configured so that its distal end has a diameter smaller than that of the proximal end, wherein the holding member has an engaging surface facing one side along the axial line direction to hold the distal end of the coil spring.

4. A valve assembly comprising:
-
a valve attached to a cylinder head in a movable manner along its axial line direction so as to selectively fluidly connect or close between a combustion chamber and a gas line; a plate-like holding member provided at the valve in a relatively immovable manner along the axial line direction, the holding member having an engaging surface facing one side along the axial line direction; a plate-like retainer externally inserted around the valve in a relatively movable manner along the axial line direction in a state where its inner peripheral surface slidably contacts an outer peripheral surface of the valve, the retainer having a contacting surface that faces the other side along the axial line direction and contacts the engaging surface of the holding member so that an end of a movable area of the retainer towards the other side along the axial line direction is defined; and a coil spring externally inserted around the valve in a state where its proximal end is directly or indirectly engaged to an external surface of the cylinder head, the coil spring being configured so that its distal end has a diameter smaller than that of the proximal end, wherein the retainer has a supporting surface facing the one side along the axial line direction to hold the distal end of the coil spring. - View Dependent Claims (5)
