Abstract
A coupler plate for a multi-valve system of an internal combustion engine. The coupler plate includes an elongated planar body and through holes on opposite ends. The through holes may be either closed or open ended, and of sufficient size to insert valve stems of valves for an internal combustion engine valve system.
Claims8
A mufti-valve system, comprising:
- at least two valves;
- a valve bridge configured to transmit an actuation force to each of the at least two valves;
- valve springs, at least one valve spring disposed around at least one corresponding valve;
- at least one retainer element arranged to retain at least one of the valves and springs;
- and
- at least one coupler plate, the at least one coupler plate being a planar element arranged to couple the valves independent of the valve bridge, wherein the at least one coupler plate deforms when one of the valves moves in variation to the other and generates a reaction load tending to reduce the variation, the reaction load acting between the at least two valves such that the reaction load does not act on the valve bridge.
A coupler plate for a valve system for an internal combustion engine, the valve system having at least two valves, a valve bridge configured to transmit an actuation force to each of the at least two valves, valve springs, at least one valve spring disposed around at least one corresponding valve, at least one retainer element arranged to retain at least one of the valves and springs, the coupler plate comprising:
- a rigid planar element, at least two holes formed at opposite ends of the planar element to receive valves of the valve system to couple the planar element to each of the valves, wherein the at least one coupler plate deforms when one of the valves moves in variation to the other and generates a reaction load tending to reduce the variation, the reaction load acting between the at least two valves such that the reaction load does not act on the valve bridge.
