摘要： PROBLEM TO BE SOLVED: To provide a cushion valve which can be integrated in two pilot lines and directly connected to a tank.SOLUTION: A cushion valve 1 comprises a housing 2 including a pair of primary chambers 25A and 25B and a pair of secondary chambers 26A and 26B. Within the housing 2, a first spool 3 and a pair of second spools 4A and 4B are arranged, and energization components 6 are arranged between them. The first spool 3 includes a first internal passage 35 formed to communicate with a tank port 23. Each of the second spools includes a land part 43 for opening/closing an opening (27A or 27B) formed between the primary chamber and the secondary chamber, and each of the second spools includes a second internal passage 45 formed to include a contraction 46. When one second spool moves towards the first spool 3, the first internal passage 35 is communicated with the secondary chamber on the side of the other second spool.
