Abstract

PURPOSE:To prevent the abnormal rise of pressure and reduce the bypass flow rate by combining a valve which does not cover a low pressure passage and the first and second passages at the same time by a valve body and a valve which covers these passages at the same time, when a plurality of four-way selecting valves are arranged in parallel. CONSTITUTION:Main valves A and B are connected in parallel, and are selected at the same time by a pilot valve D and a subvalve C. The valve pieces 10 and 10b driven by pistons 12 and 13 are arranged in the valve pieces 1 of the main valves A and B. In the transient state of switching, the valve body 10 of the main valve A is formed narrow so as not to cover a low pressure passage 6, the first and second passages 7 and 8, and the high pressure fluid supplied from a high pressure passage 3 is not divided, and the abnormal rise of the pressure is prevented. The valve body of the main valve B is formed wide, and since the low pressure passage 6, the first and second passages 7 and 8 are covered at the same time during the transient of selection, the bypass flow which directly flows into the low pressure passage 6 from the high pressure passage 3 is reduced.
