<p>A centrifugal pressure regulator comprises a pair of pistons slidable within a bore and moves in one direction by the action of a coiled spring and by centrifugal force imparted to the pistons as the body in which the bore is located rotates. The outer ends of the two pistons are subjected to the outlet pressure of a pump and the piston adjacent the spring is smaller in diameter than the other piston. The space between the pistons is vented to a drain and in the wall of the bore there is formed a spill port. The smaller of the pistons controls the size of the port which communicates with the outlet of the pump. The outlet pressure of the pump is controlled in accordance with the position of the pistons by spilling fuel through the port, the amount of fuel spilt depending on the effective size of the port.</p> |
