Abstract

515,231. Fuel-injection pumps. L'ORANGE, R. May 28, 1938, No. 16011. [Class 102 (i)] An unloaded or lightly loaded valve 1 is arranged to co-operate with two seats 2, 4 so that it is lifted from seat 2 and engages seat 4 before the main delivery valve 3 of a fuel injection pump opens, to cause a preliminary injection. The stem 1c may be guided as shown or in the body of valve 3. Fig. 3 shows an arrangement wherein the seat 2 is arranged within the valve 3 and the seat 4 is on a member 7 which guides the valve 1 and is held in position by the spring 6. In a modification of this last construction, the valve may be in the form of a ball.
