ABSTRACT:
A pressure regulation valve is disclosed which comprises a housing including first and second ports, a support for slidably supporting a tubular member defining a valve seat against which a valve element is engageable. The tubular member and valve element are spring biased into engagement with one another. In use, the application of pressurized fuel to the first port pushes the tubular member against the stop, the valve element being able to leave the valve seat in order to permit fuel flow through the valve. If the second port is at a higher pressure than the first port, the valve element moves into engagement with the valve seat, the application of a high pressure resulting in the valve element and tubular member moving until the valve element engages the support, further movement of the tubular member permitting fuel flow through the valve from the second port to the first port.
