Abstract
751,160. Fuel-injection pumps. DAIMLERBENZ AKT.-GES. May 11, 1954 [May 11, 1953], No. 13795/54. Class 102(1). The delivery valve of a fuel-injection, pump has a portion 22 having a flat seat 23 seating on a washer 20 at the end of the pump cylinder and a portion 17 having an edge 26 which controls delivery ports arranged radially in the valve guide. The ports 27 may be spaced axially as shown at 27a, 27b and 27c in Fig. 2 and be of different sizes. Alternatively a single slot of helical shape may be employed. In a modification, the valve may have a tapered portion 22a which restricts a flow through the delivery port or ports. The valve prevents drip at the injection nozzle and reduces the unloading effect on the delivery line at low speeds.
