Abstract
A shoe housing,is connected to and rotatable together with an input shaft. A vane rotor,is connected to an output shaft and accommodated in shoe housing,so as to cause a rotation within a predetermined angle with respect to shoe housing,Vane rotor,and shoe housing,cooperatively define hydraulic chambers,and,whose volumes are variable in accordance with a rotational position of vane rotor,with respect to shoe housing,A locking member,is accommodated in vane rotor,and shiftable in a direction parallel to a rotational axis common to shoe housing,and vane rotor,And, an engaging bore,formed on a front plate,secured to shoe housing,receives locking member,through a tapered surface. With this arrangement, it becomes possible to provide a control apparatus for varying a rotational or angular phase between the input and output shafts, while adequately maintaining the durability of the apparatus with a simple configuration easy to manufacture and suitable for downsizing without causing hammering noises or increasing operational resistances.
