HIGH-PRESSURE ACCUMULATOR SUCH AS HIGH-PRESSURE FUEL ACCUMULATOR

摘要

The invention relates to a high-pressure accumulator, in particular a high-pressure fuel accumulator, comprising a hollow base body 1 and at least one transversal bore 2 with a connection opening 3 to the interior chamber 4 of the base body 1. To increase the pressure resistance, one or more notches 5 and/or recesses 6 for relieving the stress on the pressurised high-pressure accumulator are introduced into the exterior and/or interior surface of the hollow base body 1, said notches 5 and recesses 6 being preferably introduced in the vicinity of the transversal bores 2 or extending in an axial direction in close proximity to said transversal bores 2.
