WIPO Patent Application WO/2024/014083
Kind Code:
A1
Abstract:
A hydraulic system (1) according to one embodiment includes: a variable displacement type first bidirectional pump (2) that is connected to a head-side chamber (4h) of a single rod cylinder (4) with a head-side line (21), and connected to a rod-side chamber (4r) of the single rod cylinder (4) with a rod-side line (22); and a variable displacement type second bidirectional pump (3) that is connected to the head-side line (21) with a supply/discharge line (31). The hydraulic system (1) further includes: a low-pressure selection valve (6) that is connected to the head-side line (21) with a first discharge line (61), and connected to the rod-side line (22) with a second discharge line (62); and a position detector (9) that detects the position of the low-pressure selection valve (6).
