Rocker arms are not required, and so a pump rotor is used. The special pressure plate has porting to feed pressure under the vanes thus eliminating the need for shuttle valves (see Figure 5). Pressure 30 psi higher than system pressure is obtained by Rocker placing a 30 psi check valve between the pump and directional valve and sampling pressure ahead of the check... -
