<p>The hydraulic control device has a pressure regulator (32) pressurized by a constant force (Px) in the opening direction, lower pressure in closing direction downstream of the inlet metering orifice (40,44) and upstream of outlet metering orifice (42,46). The discharge flow of the pump (8) is adjustable as a function of larger of the two pressures.</p> |
