If there is a failure of pressure in the primary brake circuit, the proportioning valve assembly (40, 140) actuates the differential area piston (50, 150) to permit fluid flow to bypass the piston (50, 150) and be communicated directly to the rear brakes of the vehicle.GAISER ROBERT, ...

Figure 7-16.Pilot-controlled reducing valve. The pilot valve consists of a poppet (1), a spring (2), and an adjusting screw (3). The valve spool assembly consists of: a valve spool (10) and a spring (4). Fluid under main system pressure enters the inlet port (11) and under all...
The flow characteristic is normally given at steady state, with the inlet at a constant, carefully controlled pressure. The flow characteristic depends only on the valve and can be linear or nonlinear. To capture the flow characteristics, use theOpening characteristicparameter: ...
