Abstract: Within a cam ring (8), a rotor having a plurality of vanes (27) is eccentrically disposed. A metering orifice (136) is provided halfway on a discharge passage (135) of pressure fluid discharged from the pump, and a control valve is activated due to a pressure difference between the upstream and downstream sides of the metering orifice (136). A fluid pressure of the first fluid pressure chamber (21) is controlled by activation of the control valve (123). The second fluid pressure chamber (22) is shut off from the control valve (123) to introduce a pressure on the suction side at any time. To return the cam ring (8) in a direction of expanding a pump chamber (11), an internal pressure of the cam ring (8) is applied in the return direction.

A joint member is connected to the end section of the slidable shaft. A stopper member is disposed between the slidable shaft and the joint member. Here, the end section of the slidable shaft is cutout to form an axial engagement surface. The slidable shaft and the joint member are connected in a condition where the end face of the slidable shaft is in contact with the end face of the joint member so as to from a groove between the axial engagement surface and the joint member. The stopper member is formed annular and has an engagement section formed along its inner periphery. The engagement section is fitted in the groove so that the stopper member is prevented from at least an axial movement.

Abstract: An electric power steering apparatus is disclosed. The apparatus features a first shaft and a second shaft connected by an elastic member. A first detecting member is coupled to the second shaft, and made of magnetic material with a plurality of radial notched portions defining a number of slots. A pair of second detecting members are coupled to the first shaft and positioned on both sides of the first detecting member, and made of conductive and non-magnetic material with a plurality of radial notched portions defining a like number of slots. A pair of detecting coils are axially positioned on both sides of a set of the first and second detecting members. A housing accommodates the first and second detecting members, the detecting coils, and holds yokes in a fixed position. The largest outer diameter of the first shaft is smaller than each of the inner diameters of the first detecting member, the second detecting member and the yokes, thereby improving the assembling of the electric power steering apparatus.
