The housing includes a valve bore, two circular housing control edges, two inlet channels fluidically connected to the bore, and an outlet channel opening into the bore between the inlet channels. The piston includes two control collars, a piston neck, and piston control edges that delimit the collars from the neck, and that have circular shapes with a recess. The recess has a portion that, in a cross-sectional plane perpendicular to an axis of the piston, is constant and sized such that a flushing quantity is reduced when the portion of the recess is situated in a region of a corresponding housing control edge relative to a quantity when the piston is in an end position. The collars guide the piston so as to be longitudinally displaceable in the bore, and are spaced apart by the neck.
