<p>The invention relates to a pneumatic load-controlled brake valve (1) for operating at least one independent pneumatic brake of a rail vehicle in accordance with a pilot pressure (Cv) and a current load state of a particular car, comprising a first piston (2), to which a brake cylinder pressure (C) is applied and which has a first piston rod (3), a second piston (4), to which the pilot pressure (Cv) is applied and which has a second piston rod (5), wherein the two piston rods (3, 5) interact with a balance beam (6) in order to actuate a double-seat valve (7) for feeding air into and allowing air to escape from a brake cylinder (8), wherein the balance beam (6) interacts with an adjustment nut (9) on an adjustment device (10), the position of which nut in relation to the balance beam (6) can be changed by means of an axially movable feeler (12) of a feeler device (13) for registering the load state of the particular car, said feeler having a feeler tip (11) at a distal end directed downward, wherein the feeler device (13) comprises a damper piston (16), which is located in a housing (14) and connected to a piston rod (15) and axially movable within a cylinder (17) formed in the housing (14), and a decoupling spring (18) for force decoupling that acts on the piston rod (15) indirectly and a restoring spring (19) that acts on the axially movable feeler (12) indirectly are arranged between the axially movable feeler (12) and the piston rod (15).</p> |
