Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
121 words
An exhaust gas recirculation valve suitable for mounting in a base having a pair of apertures and a recess connecting said apertures, said valve comprising a seat member having a portion adapted for closing said recess and also having a projection adapted to be received in one of said apertures, said projection having a cavity with an orifice adapted to open through said one aperture and a window adapted to open to said recess to thereby define an exhaust gas flow path between said apertures, said seat member having a seat surrounding said orifice, said valve further comprising a pintle aligned with said seat and an actuator for positioning said pintle to control the flow of exhaust gases through said seat.
Claim 2
Dependent Claim
121 words
An exhaust gas recirculation valve suitable for mounting in a base having a pair of apertures and a recess connecting said apertures, said valve comprising a seat member having a portion adapted for closing said recess and also having a projection adapted to be received in one of said apertures, said projection having a cavity with an orifice adapted to open through said one aperture and a window adapted to open to said recess to thereby define an exhaust gas flow path between said apertures, said seat member having a seat surrounding said orifice, said valve further comprising a pintle aligned with said seat and an actuator for positioning said pintle to control the flow of exhaust gases through said seat.
Claim 3
Dependent Claim
114 words
The combination of an exhaust gas recirculation valve and a base, said base having a pair of apertures and a recess connecting said apertures, said valve comprising a seat member having a portion closing said recess and also having a projection received in one of said apertures, said projection having a cavity with an orifice opening through said one aperture and a window opening to said recess to thereby define an exhaust gas flow path between said apertures, said seat member having a seat surrounding said orifice, said valve further comprising a pintle aligned with said seat and an actuator for positioning said pintle to control the flow of exhaust gases through said seat.
Claim 4
Dependent Claim
