形ベーンポンプ。(1) A pump in which a cam ring is housed in a pump housing so as to be linearly displaceable in the radial direction, a rotor is rotatably housed in the cam ring, and a plurality of vanes partition the rotor and the cam ring. In a variable displacement vane pump, an orifice' is formed in a pressure fluid passage which forms a chamber and sends pressure fluid to the outside from the pump chamber, and the longitudinal pressure of this orifice acts on the cam ring to displace the cam ring. , the cam ring has a control surface that faces the inner peripheral surface of the pump housing with a predetermined gap therebetween and is formed parallel to the direction of displacement of the cam ring, and a control pin with a diameter equal to or larger than this gap is attached to the cam ring. The control pin is supported on the Ponzino 1 housing so that its outer circumference abuts the control surface and is parallel to the rotor axis, and the orifice is formed between the small diameter portion formed on the control pin and the control surface. Characteristic variable displacement vane pump.
びに高さの制御突起を有することを特徴とする実用新案
登録請求の範囲第１項記載の可変容量形ベーンポンプ。(2) The variable displacement vane pump according to claim 1, wherein the control surface has a control protrusion having a width and height that can enter the small diameter portion.
