Abstract

The regulator is designed to control the flow of a pressurised liquid which operates a hydraulic jack of a servo drive. The regulator is operated by two elements working together. The first of these elements has a cylindrical body with flats formed in it. Each of the flats has a slot between its lateral sides and perpendicular to them, the slot being situated midway between the extreme edges of the flat. The first element has two pairs of parallel and diametrically opposed flats formed in the cylindrical body. The first pair of flats being perpendicular to the second pair.
