Abstract
The driver's brake valve device for indirectly acting, pneumatically and electro-pneumatically controllable air brakes has an electro-pneumatic pressure switch (18) with a contact element (65) for the switching of electrical brake and release contacts (67a, 67b and 66a, 66b). The contact element (65) can be directly shifted from an opening position for the brake or release contacts (67a, 67b and 66a, 66b respectively) into a closed position of the latter by means of mechanical coupling, by way of a camshaft (15) with a cam disc (54), to a driver's brake lever, and can subsequently be pneumatically returned into the open position by pneumatic feedback of the correspondingly varying main air line pressure. The pressure switch (18) has a chamber (49) for the storage, during braking, of a pilot control pressure present in the drive position and monitored by a pressure governor of the driver's brake valve device. The pressure switch (18) has an internal piston (55) moving the contact element (65), which piston is acted upon on one side by a spring (57) and the main air line pressure fed into a pressure chamber (48) by way of a line (68) and a chamber (50), and on the other side by the pilot control pressure. This pressure switch construction permits a precise electro-pneumatic control even of small pressure changes.
