Abstract

1305930 Valves ROBERT BOSCH GmbH 9 April 1970 [9 April 1969] 16818/70 Heading F2V [Also in Division F1] Electromagnetically actuated valves 17, 18 control the supply of fuel to, and spillage from, the pumping chamber of a fuel injection pump. Fuel enters the pumping chamber via a passage 14 controlled by valve 17 the member 20, 22 of which is normally held in the open position by spring 21. On activating coil 19, member 20 is retracted and its head 22 abuts seat 23. Valve 18 is normally held in the closed position wherein its head member 28 is pressed against a seat 29 by means of a member 26 and spring 27. On activating coil 25 member 26 is retracted and fuel pressure from the pumping chamber in bore 31 lifts head 28 from its seat 29, thus allowing annular grooves 32 and 33 on the head and surrounding bushing 34 to communicate. Fuel from the pump chamber flows via grooves 33, 32 and a bore in the head 28 to a passage 15 leading back to the pump inlet chamber.
