Document Type and Number:
Japanese Patent JPH0263107
Kind Code:
B2
Abstract:
A fuel injection pumping apparatus of the rotary distributor type has a distributor member which is also axially movable to determine the allowed outward movement of the pumping plungers and hence the amount of fuel supplied to the associated engine. The extent of outward movement is determined by inclined stop surfaces which co-operate with complementary surfaces on shoes associated with the plungers. In order to minimize axial movement of the distributor member when the shoes engage the stop surfaces a chamber to which liquid is supplied to vary the axial setting of the distributor member, is locked off from fluid supply and drain passages, by a servo valve 41 when the correct position of the distributor member is obtained. A hydraulic lock is thus created in the chamber.
