Abstract
A fuel supply system includes a source of oxidizer providing oxidizer at an oxidizer pressure, a source of fuel providing fuel at a fuel pressure, and a fuel pressure regulator referenced to the oxidizer pressure. The fuel pressure regulator receives the fuel from the source of fuel at the fuel pressure, and discharges the fuel at an outlet pressure that is lower than the fuel pressure and proportional to the oxidizer pressure.
Claims14
A fuel supply system comprising:
- a source of oxidizer providing oxidizer at an oxidizer pressure of at least 400 psi;
- a source of fuel providing fuel at a fuel pressure;
- and a fuel pressure regulator having an inlet port and an outlet port, said fuel pressure regulator receiving the fuel from said source of fuel through said inlet port at said fuel pressure, and said fuel pressure regulator being referenced to said oxidizer pressure to discharge the fuel through said outlet port at an outlet pressure that is lower than said fuel pressure and proportional to said oxidizer pressure.
A fuel pressure regulator for use with a source of fuel, an engine, and a source of oxidizer providing oxidizer at an oxidizer pressure, the regulator comprising:
- an inlet port adapted to communicate with the source of fuel to receive fuel therefrom;
- an outlet port adapted to communicate with the engine to provide fuel thereto;
- and
- at least one pressure responsive member having a first surface area exposed to the oxidizer and a second surface area greater than the first surface area and exposed to the fuel within the regulator, and operable to adjust the pressure of fuel flowing out of said outlet port to be less than and proportional to the oxidizer pressure.
