Abstract
Provided is a roll over fuel-vapor valve is provided including a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between the inlet port and the outlet port and being displaceable between an open position and a closed position the hosing further comprising a fluid flow channel extending along a top portion thereof and having a first end and a second end, wherein the outlet port extending into the channel such that in the open position fluid flow is facilitated between the valve inlet port and the channel.
Claims19
A roll over fuel-vapor valve comprising a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between said valve inlet port and said valve outlet port and being displaceable between an open position and a closed position said housing further comprising a fluid flow channel extending along a top portion of the housing and having a first end and a second end, wherein said valve outlet port extending into said channel such that in said open position fluid flow is facilitated between said valve inlet port and said fluid flow channel;
- wherein said housing is a tubular housing accommodating a cage assembly fixedly disposed therein and defining an inside space accommodating said float member;
- wherein the cage assembly comprises a pair of side plates configured for sealing engagement with walls of a fuel-vapor tube segment at respective sides of the fuel-vapor tube segment, a bridging member extending between the side plates and spaced from an inside surface of the tube segments and constituting the channel and a base member disposed between the side plates and configured with a boss supporting a float member biasing spring.
A fuel-vapor system configured with one or more fuel-vapor tube segments and at least one roll over fuel-vapor valve comprising a housing defining a valve having a valve inlet port extending through a wall of the housing and a valve outlet port and a float member disposed between said inlet port and said outlet port and being displaceable between an open position and a closed position said hosing further comprising a channel extending along a top portion thereof and having defining together with an inner surface of said fuel-vapor tube segments a channel inlet and an channel outlet wherein said outlet port extending into said channel such that in said open position fluid flow is facilitated between said valve inlet port and said channel outlet;
- wherein said housing is a tubular housing accommodating a cage assembly fixedly disposed therein and defining an inside space accommodating said float member;
- wherein the cage assembly comprises a pair of side plates configured for sealing engagement with walls of a fuel-vapor tube segment at respective sides of the at least one inlet port, a bridging member extending between the side plates and spaced from an inside surface of the tube segments and constituting the channel and a base member disposed between the side plates and configured with a boss supporting a float member biasing spring.
