PLANT TO MANUFACTURE ROTARY VALVE FOR HYDRAULIC POWER-ASSISTED STEERING GEAR

摘要

FIELD: mechanical engineering. SUBSTANCE: machine to measure angular position of edges of axial grooves made in cylindrical surface of driving shaft or sleeve of valve has aid to deliver fluid medium connected to pressure chamber, aid to feed fluid medium into pressure chamber, aid to provide for relative rotation of delivery aid and measured part and aid to measure relative angular position of part and delivery aid. The latter is manufactured in the form of shoe with arc-like surface and through slot located in parallel to axis of part. Slot communicates with pressure chamber. Plant also includes aid to provide contact of arc-like surface of shoe with surface of part having grooves and aid to measure degree of limiting flow of fluid medium through slot. Arc-like surface of shoe can be convex or concave. EFFECT: increased functional efficiency of plant. 7 cl, 15 dwg
