ZWEISTUFIGES BREMSSTEUERVENTIL
A large piston (50) initially acts to supply a large volume of braking fluid to a brake port (30) by way of a check valve (118) disposed in a small piston (52) working in a chamber (104) in communication with the brake port (30). When the pressure in this chamber (104) reaches a certain level a pin...

| description | A large piston (50) initially acts to supply a large volume of braking fluid to a brake port (30) by way of a check valve (118) disposed in a small piston (52) working in a chamber (104) in communication with the brake port (30). When the pressure in this chamber (104) reaches a certain level a pin (132) lifts a relief valve ball (136) off its seat and vents the large piston chamber (88) to a reservoir line (22), via various passages in the large piston (50) and the valve body. The poppet (120) of the check valve and the ball (136) of the relief valve act against oppositely facing seats in a bore through the small piston and the large piston chamber (88) communicates via a passage (114) with this bore, inbetween the two valve seats. Additional venting of the large piston chamber (88) is provided by a direction sensitive valve (80, 86) which provides a venting passage when the large piston (50) is retracting. |
