Abstract

893,621. Fuel-injection pumps. CESKOSLOVENSKE ZAVODY NAFTOVYCH MOTORU PRABA NARODNI PODNIK. June 22, 1960 [June 30, 1959], No. 21910/60. Class 102(1). A diesel fuel-injection pump has two stage injection, obtained by interrupting the injection by connecting the pump pressure space to an overflow duct 5 for a short part of the discharge stroke via linked recesses 7, 12 in the piston and cylinder respectively, the lower edge 8 of the cylinder recess lying below the upper edge of the fuel inlet duct 4, but above the upper edge of the overflow duct. The piston recess may be annular, or segmental, Figs. 2, 3 (not shown). In another embodiment, Fig. 4 (not shown), the cylinder recess extends transversely to the longitudinal axis of the cylinder and is shut off by a stopper 13, Fig. 4 (not shown).
