In internal combustion engines operating with solid fuel injection and which are v erned by a relief valve, and in which the de very valve is fitted in the injection piping, this delivery valve is generally separatedLfrom the fuel pump either by a greater or lesser distance. Th s delivery valve has aspecial dut to perform upon interruption. of the fue pump pressure stroke, as the overflow of the compression or explosion pressure from the cylinder into the suction part of the fuel pump must be avoided; otherwise the en 'ne is put out of service. But it must be ta eninto consideration that even with the very best workmanship and most careful attention, there is always the possibilit that this valve might suddenly become de ective'and cause interruptionin working, which is espc'-.
.c'ially annoying with non-stationary motors because it causes great inconvenience to re-' I set the valve while the vehicle carrying the motor is 'in use upon the track or road, and in addition occupies too much time. With marine motors, the conditions are similar, as a stop-must be avoided. In this invention, I it has been endeavoured to construct the valve in such away that the valve and its seating can be easily taken out of the valve casing achieve by having the bod'yof the valve seating readily removable and interchan eable in a sleeve which is connected with t e fuel pump and guided in a bore of the valve 7 casing and detachable with the'latter." As
compared with the hithertoknown valves,
' this construction has the further advantage when the screw cap and can be replacedby spare parts which are perfectl "ground and readyfor use. This is "The valve'seating Fa is fitted looselyinto the cylindrical bore of'the sleeve c which is arranged ina piping [2 connecting the fuel pump .m to the cylinders n. 1 The sleeve 0 fits loosel into the cylindrical bore of the valve casing a'ndis connected with this b a screw cap .e. The body ofthe valve seat a is made oil-tight by means of packing rings ff, which are fitted on both sides" of a flange a :""on the body of the valve seating and are compressed by the sleeve 0,
e is tightened to efiect. operative connection. The valve g isguidcd in the valve boreh? and keptlon. its seating .by aspiral spring 6. ""j andk are two delivery pipes leading from the valve casing to the injection nozzles of the cylinders.
The under art of the bore h. of the valve seating is for shaped, and is in connection with a circular channel Z of the valve body,"
which is definedby the rims l and Z? which together with the inner bore of the sleeve c serve as a strainer for the fuel.
In order to replace a damaged valve, the screw cap e is'loosened and unscrewed from the valve casing fd, then the sleeve 0 with the valve seating,a, and the v"valve 'g are withdrawn fromthe valve casing d b bendthepipe b and the valve seat wit valve 9 therein may be readily and quickly re-- moved and exchanged for another valve seating and valve unit,which may beasreadily inserted in place after which the screw cap ,e.may be sore ed back upon the member d to connect t iefparts again in operative connection. i
