Abstract
PURPOSE: To shorten an overall length of a power steering device, by converting a relative rotation displacement produced between an input and output shafts into a displacement of a rocking shaft supporting a pinion receiving the rotation from both shafts, and by displacing a spool valve conjointly and in synchronism with said displacement.
CONSTITUTION: A control valve mechanism 5 is equipped with a rod 20 and a spool valve 30 which are slidably supported at a housing 12. The vertical displacement of them feeds a hydraulic oil circulating through ports 32 and 33 to a power cylinder 7 via a duct 35 or a duct 37. The control valve mechanism 5 and a motion conversion mechanism 40, which converts a relative rotation displacement produced between the input and output shafts 9 and 10 into a straight line displacement and transmits it to the spool valve 30, are located between the input and output shafts 9 and 10. In the mechanism 40, a rocking shaft 41 inclines due to a difference between rotation amounts applied to pinions 43 and 44 when the relative rotation displacement is produced between the input and output shafts 9 and 10, the rod 20 and the spool valve 30 being displaced following said inclination. A neutral position can thus be held.
