摘要:
A pressurizing and pressure regulating valve (12) is provided. In one embodiment, the pressurizing and pressure regulating valve includes a sleeve (14), a first flow passage (18, 24, 30) formed through the sleeve, a second flow passage (20, 26, 30) formed through the sleeve, and a piston (16) slidably disposed in the sleeve. The piston is configured to move between: (i) a pressurizing position wherein the piston impedes fluid flow through the first flow passage, and (ii) a pressure limiting position wherein the piston impedes fluid flow through the second flow passage. A sensing chamber (42) is fluidly coupled to the first flow passage and configured to receive pressurized fluid therefrom. The piston is configured to move from the pressurizing position to the pressure limiting position when the pressure within the sensing chamber exceeds a predetermined minimum pressure.
