Valve structure for hydraulic circuit |
摘要 |
A valve comprises a spool with a land received in a bore of a valve body. The land is formed with at least one transfer passage. The land and cylindrical inner wall of the bore cooperate with each other to prevent any passage other than the transfer passage from opening between an inlet port and an outlet port. The transfer passage is always open to the outlet port and selectively uncovered by the cylindrical inner wall to communicate with the inlet port in response to movement of the spool.
