Oil pressure control device for automatic transmission

When an engagement pressure (PSL2) is supplied to a second working oil chamber (23b), a spool (23p) is locked in a first position, and a switching pressure (PSLP) is able to adjust a belt clamping force without switching the position of the spool (23p), and when the engagement pressure (PSL2) is not...

Beschreibung
Zusammenfassung:	When an engagement pressure (PSL2) is supplied to a second working oil chamber (23b), a spool (23p) is locked in a first position, and a switching pressure (PSLP) is able to adjust a belt clamping force without switching the position of the spool (23p), and when the engagement pressure (PSL2) is not supplied to the second working oil chamber (23b), the spool (23p) is not locked in the first position, and the switching pressure (PSLP) is able to switch the spool (23p) to a second position in opposition to a biasing member (23s). 通过将接合压(PSL2)供给到第二动作油室(23b)，阀柱(23p)被锁定在第位置，切换压(PSLP)不对阀柱(23p)的位置进行切换而能够对带夹压力进行调压，另方面，通过不将接合压(PSL2)供给到第二动作油室(23b)，阀柱(23p)未被锁定在第位置，切换压(PSLP)克服施力构件(23s)将阀柱(23p)切换到第二位置。
