Abstract: A lubricant supply limiting device (1') for a lubrication system, wherein at least one fixed throttle (F) and a servo pressure controller (3) provided with a variable throttle (D) are disposed in the flow path, and wherein an adjustment member (6') for the variable throttle (D) is subjected to the resilient action of an actuator, is provided with a proportional solenoid (15) acting as the actuator for selectively adjusting the lubricant flow to the demand at specified lubrication points. A proportional solenoid (15) is moreover advantageous for general use in servo pressure controllers to act on the adjustment member thereof in a manner permitting the pressure differential maintained by the servo pressure controller and determined by a fixed throttle to be varied.
