Abstract

FIELD: automatic control. SUBSTANCE: device has housing 1, radial input channel 2, drain channel 3 and axial channel 4, sleeve 5 which has radial input channel 6 and drain channel 7, regulating body which is designed as piston 8 with axial channel 9, inlet holes 10 and drain holes 11 which are made in two rows of holes which diameters in each row D1, D2, D3, D4 conform to condition of D1/D2 = D3/D4 = 0.2...0.3; L1/D2 = L2/D3 = 0.38...0.63, where L1, L2 are distances between centers of holes in rows of inlet and drain holes. Device may be used as transducer of input electric signal to pressure of liquid or gas at output of system which controls hydraulic and pneumatic final-control mechanisms. EFFECT: improved regulation characteristics. 1 dwg

The invention relates to automatic control, is intended to control the pressure of a liquid or gas and can be used in hydropneumatic systems as a unit that converts an input electrical signal to a pressure of a liquid or gas at the output of a system that controls hydraulic and pneumatic actuators. Purpose: improvement of adjusting characteristics. The inventive pressure regulator comprises a housing 1, radial inlet 2, drain 3 and axial, as well as output 4 channels, a sleeve 5 with radial inlet 6 and drain 7 channels, a regulating organ-piston 8 with an axial channel 9, pressure 10 and drain II holes made each in the form of two rows of holes with diameters in each row D1, D2, D3, D4 with the ratio D1 / D2 = D4 / D3 = 0.2 ... 0.3, Ll / D2 = L2 / D3 = 0 , 38 ... 0.63, where LI, L2 are the distances between the centers of the holes of the rows of pressure and drain holes.
