FIELD: hydraulics; hydraulic automatic control devices; hydraulic drives of various application. SUBSTANCE: pressure regulator has housing 1, radial cylindrical inlet and outlet channels 2 and 3, respectively, cylindrical axial bore 4, cylindrical spool 5, spool first end face 6, chamber 7, space 8, radial channel 9, outlet pressure space 10, belts 11,12, spool second end face 13, spring 14, support member 15. Variable throttle of pressure regulator is formed by radial cylindrical inlet channel 2 intersecting cylindrical axial bore 4 of housing 1 and spool belt 12 with tapered surface. EFFECT: increased accuracy of output pressure control owing to provision of smooth flow rate characteristic. 1 dwg |
