Abstract (en)

[origin: WO2014198387A1] The invention relates to a quantity-limiting valve (1) for an injection system (6) of an internal combustion engine (8), comprising an inflow region (7), an outflow region (9), and a piston (13) which is movably guided in a cylinder (11) and by means of which the inflow region (7) is separated from the outflow region (9). The inflow region (7) and the outflow region (9) are fluidically connected via an overflow channel (15) which passes through some areas of the piston (13) and via a current path (17) arranged between a circumferential surface (19) of the piston (13) and an inner surface (21) of the cylinder (11). An end surface (25) of the piston (13) is preloaded against a stop surface (27) of a stop element (29) in a first functional position. An underflow structure (39) is formed in a region where the end surface (25) contacts the stop surface (27) in the first functional position, said underflow structure comprising at least one intermediate area (41), which is fluidically connected to the inflow region (7), between the piston (11) and the stop element (29).
