Abstract
A novel spatial arrangement of valve ports and hold-down bolt holes in the body of an exhaust gas recirculation valve, wherein the centers of the ports are between and aligned with the centers of the bolt holes, thereby producing maximum sealing force around the ports against the surface to which the valve is bolted, such as the exhaust and intake manifolds of an internal combustion engine.
Claims7
A valve body for a pintle-type valve wherein the operational axis of the valve is contained in a plane containing the maximum attachment force normal to the attachment surface of said valve when said valve is attached on said attachment surface to a substrate.
A pintle-type valve assembly, comprising:
- a) a valve body wherein the operational axis of the valve is contained in a plane containing the maximum attachment force normal to the attachment surface of said valve when said valve is attached on said attachment surface to a substrate;
- and
- b) an actuator attached to said valve body for actuating said valve.
An exhaust gas recirculation valve assembly, comprising:
- a) a valve body wherein the operational axis of the valve is contained in a plane containing the maximum attachment force normal to the attachment surface of said valve when said valve is attached on said attachment surface to a substrate;
- and
- b) an actuator attached to said valve body for actuating said valve.
An internal combustion engine, comprising an exhaust gas recirculation valve having a valve body wherein the operational axis of the valve is contained in a plane containing the maximum attachment force normal to the attachment surface of said valve when said valve is attached on said attachment surface to a substrate.
