Tidbromsventil (Elektrifiering/elektrisk drift)

av -ch-, Saturday, February 07, 2015, 10:03 (3595 dagar sedan) @ MAWJ1

Tidbromsventilen på äldre dragfordon fram till och med Ra var mekanisk, medan den senare generationen styrdes genom en YBL-ventil.

Ybl-ventilen var väl av model 21b. En standare EP-ventil med påbyggd luftbehållare där utlösningstiden styrdes av en trång dysa där luften skulle pysa ut innan huvudledningen avluftades.
På en del fordon (Y6, 7 och8 bla) styrdes tiden av en kontakt kopplad till en hydraulisk dörrstängare som var sammanbunden med fotpedalen. Sattes vanligtvis ur bruk med lokförarportföljen eller ett bromsblock :-)
