Darrell Todd Wiley - Summerville SC, US

Assignee:

ITT Manufacturing Enterprises, Inc. - Wilmington DE

International Classification:

F02M 37/00

US Classification:

123434

Abstract:

A control module for regulating and delivering quantities of compressed air and fuel to a fuel reformer is described herein. The control module includes a housing, a compressed air circuit coupled to a source of compressed air, and a fuel circuit coupled to a source of fuel. Each circuit includes: (i) a flow passageway formed in the housing that extends between an inlet port that is configured to be fluidly coupled to either the source of compressed air or the source of fuel and an outlet port that is configured to be fluidly coupled to the fuel reformer, (ii) a discrete valve positioned within the flow passageway that is configured to either permit or prevent the passage of fluid through the flow passageway, and (iii) a regulator valve positioned within the flow passageway that is configured to maintain a constant pressure differential across the flow passageway.

Abstract:

A gas pressure regulator includes a body having respective inlet and outlet ports and an interior chamber defining a gas flow path. A hollow piston is moved in relation to a valve seat to create a junction through which gas is directed along the flow path to the outlet port. The piston engages a valve seat, thereby defining relative open and closed positions based on the position of the piston and the pressure of the gas, the piston being axially biased by a spring. The valve seat is attached to an adjustment member having at least one externally accessible feature to enable the axial position of the valve seat to be varied relative to the spring biased piston. In one version, the gas pressure regulator can include a heater assembly extending into the flow path adjacent the outlet port, enabling ported gas to be heated before introduction, e.g., into an engine.
