Description
Flow is allowed bi-directionally between 2 and 3, and blocked
at 4 until pressure at 1 rises to overcome the spring bias
against the spool. When this bias pressure is surpassed, the
spool shifts, allowing bi-directional flow from 3 to 4 while
blocking 2. The spring chamber is drained to 4, thus any
pressure at 4 is additive to the spring bias and pilot pressure
required for shifting.
