Abstract

1455458 Fuel injection pumps ROBERT BOSCH GmbH 28 Nov 1973 [29 Nov 1972] 55064/73 Heading F1A In a fuel injection pump comprising a piston 2 reciprocable and rotatable in a cylinder 4 to pump fuel from a working chamber 12 through a distributing passage 17, 22 successively into delivery passages 33, the delivery of fuel to a respective delivery passage 33 is terminated when a radial port 24 in the piston 2 passes out of an adjustable control sleeve 26 to allow fuel to spill from the working chamber via the distributing passage 17, 22, a respective U-shaped passage 32 in communication with the delivery passage and a piston passage 23, 20, 19 containing a check valve 30. The arrangement of passages and the valve 30 operate to maintain a residual pressure in the delivery passages 33. By arranging for the distributing passage 17, 22 to be closed to communication with each U- shaped passage 32 before the piston passage 23, 20, 19 is closed to communication therewith, pressure waves occurring in the delivery passages can be dissipated through the check valve 30. Preferably the distributing passage is closed before the commencement of the suction stroke to prevent a partial vacuum being produced in the connected delivery passage, but it may be desirable to delay such opening until the suction stroke has started. Movement of the piston 2 is produced by a cam 6 which may be shaped to cause the piston to dwell at top dead centre.
