Abstract

Invention relates to a hydraulic valve actuator. His housing (1) incorporates two connected, parallel cylindrical chambers (2) and (3) which are through opening (12) and groove (11) in housing (1) as well as through inlets and outlets (8) and (9) in covers (7) which are by the means of screws (24) fixedly attached to said housing (1), connected to oil supply. Pistons (4) are located in chambers (2) and (3) and can slide along their longitudinal axes. Part of the length of said pistons is shaped as toothed rack (13) while on pistons remaining circular surface opposite to toothed rack, 3 V-shaped grooves (15) are machined for oil supply. On remaining length of pistons (4) which retains its original circular cross section, annular grooves (22) are machined for placement of adequate sealing rings (14). Spur gear (23) is centrally, concentrically and fixedly attached to driven shaft (17) and meshed with toothed portions (13) of pistons (4). Shafts ends diameter is smaller than gears (23) tooth root diameter and onto them cylindrical bushings (18) and (19) are affixed so that together they form firm connection. Through said bushings (18) and (19) shaft (17) is supported in smooth bores (25) and (26) in housings (1) walls while sealing is ensured with sealing rings (20) placed in grooves (27) and (28) machined in said smooth bores (25) and (26).
