Abstract

1. A rapid-braking accelerator for a railway vehicle indirect-acting compressed air brake with a control piston (12) which is subjected on one side thereof to the pressure in the main air line (10) of the brake and on the other side thereof to the pressure in a control chamber (17), which communicates with the main air line (10) through a choke (16), with an accelerator valve (13, 14) which vents the main air line (10) when a predetermined excess pressure is present in the control chamber (17) effecting the control piston (12) to open the accelerator valve (13, 14), and with a valve which is controlled by a pressure acting against the force of a pretensioned spring (30) arranged in a space (35) open to the atmosphere, wherein the spring (30) is pretensioned to a force corresponding to a pressure exceeding the maximum service control pressure in the main air line (10) by a determined value, characterised by a closable by-pass channel (34) arranged in parallel to said choke (16) and a by-pass valve (31, 32) closing the by-pass channel (34), the by-pass valve (31, 32) being opened by the pressure of a high filling shock (D1, D2) against the force of the pretensioned spring (30).
