Abstract

A casing (10) has an inlet (20) and a valve chamber (40) connected to the same as well as an outlet (60). In the valve chamber (40) a valve seat (54) is arranged at the entrance of a passage (52) leading to the outlet (60) and furthermore a valve member (42) is arranged for brake fluid to flow around it. The valve member is movable in response to deceleration from an inoperative position against the valve seat (54). A barrier member (26) is arranged between the inlet (20) and the valve member (42) for flow of brake fluid around or through the same. The barrier member is movable from an inoperative position remote from the valve member (42) until it hits the valve member (42), at least approximately in the direction of movement thereof.
