Abstract
A fluid pressure regulating valve has an inlet (10) connected to a pressurized fluid source (12) and an application outlet (14). It comprises a reference piston (30) one face of which is biased by a reference force, and a regulating piston (42) upon one face of which is applied the fluid pressure at the application outlet (14). The regulating piston (42) acts as a slide valve between the inlet (10), the application outlet (14), and a low pressure fluid reservoir (18). The other faces of the pistons (30, 42) each bias a respective end of a lever (60) the fulcrum (62) of which is movable between its ends according to the biasing force generated by each of the pistons (30, 42). Such a valve is useful for power steering for vehicles.
