Document Type and Number:
WIPO Patent Application WO/2023/105719
Kind Code:
A1
Abstract:
In a straight traveling control valve 30: a spool 50 moves between a neutral position 30A and a straight traveling position 30B, said neutral position 30A being for making a third inlet port 45 communicate with a first outlet port 43 to make an upstream-side parallel channel 13a communicate with a downstream-side parallel channel 13b and for making a second inlet port 42 communicate with a second outlet port 44 to make an upstream-side neutral channel 21a communicate with a downstream-side neutral channel 21b, said straight traveling position 30B being for making a first inlet port 41 communicate with the second outlet port 44 to make the upstream-side parallel channel 13a communicate with the downstream-side neutral channel 21b and for making the second inlet port 42 communicate with the first outlet port 43 to make the upstream-side neutral channel 21a communicate with the downstream-side parallel channel 13b; and when the spool 50 is at the neutral position 30A, a hydraulic oil is allowed to flow from the first inlet port 41 to the first outlet port 43 through a bypass channel 65.
