  • Publication number: 20210199138
    Abstract: A valve unit (V) has a valve housing (50) that includes a supply oil passage (55) configured to receive operating oil from a hydraulic pump, and a pressure adjustment valve (Va) configured to adjust the pressure of the supply oil passage (55). The pressure adjustment valve (Va) includes a pressure adjustment valve body (61) configured to open and close the supply oil passage (55), a compression coil spring (62) that keeps the pressure adjustment valve body (61) at a closed position when the pressure of the supply oil passage (55) is smaller than a set value and allows the pressure adjustment valve body (61) to open when the pressure of the supply oil passage (55) is not smaller than the set value, and a restriction member (63) configured to, when the pressure adjustment valve body (61) becomes open against the urging force of the spring (62) in response to a pressure of the operating oil, abut against the pressure adjustment valve body (61) to restrict movement of the pressure adjustment valve body (61).

  • Publication number: 20210198870
    Abstract: A work machine includes a transmission case (5) extending in the front-back direction of a machine body, a first hydraulic unit (V) provided on one of mutually opposite wall portions (5a, 5b) of the transmission case (5), a second hydraulic unit (44) provided on a second one of the wall portions (5a, 5b), and a supply passage (43) configured to supply operating oil from the first hydraulic unit (V) to the second hydraulic unit (44). The first hydraulic unit (V) and the second hydraulic unit (44) are aligned to be overlapped with each other as viewed in a direction orthogonal to a case axis (X) extending along the front-back direction of the transmission case (5). The supply passage (43) extends inside the transmission case (5) in a straight line orthogonal to the case axis (X).
