Abstract
1,038,579. Manual release valve. OERLIKON-BUHRLE HOLDING A.G. May 1, 1964 [May 8, 1963], No. 18144/64. Heading F2F. A manual release valve for a braking system comprises a casing 1 with a first chamber 6 in communication with the brake pipe, a second chamber 5 in communication with atmosphere through a choke 21 and an outlet valve 9, 10 bypassing the choke and presenting a larger cross sectional area than the choke, the second chamber being connected by an inlet valve 16, 18 with an air reservoir, a slide 7 shiftable in the casing into a release position by means of a handle 13, the slide when shifted opening in succession the inlet valve and the outlet valve to establish a back pressure in chamber 5 in the period between the opening of the inlet and of the outlet valve to move a piston 2 separating the chambers to allow an abutment 12 to hold the outlet valve in the open position. A further inlet valve 17 also operable by the collar 8 on the slide controls the connection of the auxiliary reservoir with the atmosphere. The release unit is mounted under the triple valve 23.
