EQUIPRESSION DISCHARGE VALVE FOR FUEL INJECTION APPARATUS, TO BE INSTALLED IN THE INJECTION PUMP DELIVERY DUCT AND THE INJECTOR.

摘要

P a) Pressure relief valve for fuel injection equipment, to be installed in the discharge line of an injection pump and the injector. BR/ b) The invention is characterized in that the plug (7) has a collector bore (9) for the passage of the fuel, bore which is transformed on its side turned away from the element of valve closure in at least two throttle bores (10) uniformly distributed azimuthally, the longitudinal axes (11) of the throttle bores (10) forming with respect to the longitudinal axis (12) of the collecting bore (9) an angle α = 45degree and the sum of the cross-sectional areas of the throttle bores (10) is consistently smaller than the cross-sectional area of the collector hole (9). / P
