FIELD: mechanical hydraulics, possible use for controlling pressure in hydraulic systems.
SUBSTANCE: two-stepped pressure valve contains plunger, which is made two-stepped with creation of circular shelf on it, area of which is less than the area of piston, and external surface of additionally made step forms an alternating cross-section circular channel with body clamp surface, which cross-section increases from the side of shelf.
EFFECT: stable pressure at inlet independently from value of flow through the valve, expanded spectrum of flow channeled by the valve.
