  • Publication number: 20200400210
    Abstract: The invention is a liquid filled type vibration isolating device (10) which includes a partition member (16) that partitions a liquid chamber (19) within a first attachment member (11) filled with a liquid into a first liquid chamber (14) and a second liquid chamber (15), and in which a restricted passage (24), which is configured to allow the first liquid chamber and the second liquid chamber to communicate with each other, is formed in the partition member. The restricted passage includes a first communication part (26) opening to the first liquid chamber, a second communication part opening to the second liquid chamber, and a main flow passage (25) that allows the first communication part and the second communication part to communicate with each other. At least one of the first communication part and the second communication part includes a plurality of pores (26a) that penetrate a first barrier (38) facing the first liquid chamber or the second liquid chamber.

  • Publication number: 20200049224
    Abstract: A vibration-damping device (1) of the present invention includes an outer cylinder (11), an inner member (12), an elastic body (13), a partition member (17), an intermediate cylinder (31), and a dividing member (32). The elastic body connects together the outer cylinder and the inner member. The partition member divides a liquid chamber (14) into the outer cylinder into a main liquid chamber (15) and an auxiliary liquid chamber (16). An orifice passage (21) is formed in the partition member. The intermediate cylinder (31) is disposed between the outer cylinder and the inner member and connected to the elastic body. The partition member is connected to the intermediate cylinder and divides the main liquid chamber into a first main liquid chamber (15a) and a second main liquid chamber (15b). An accommodation chamber (37), a first communication hole (37a), and a second communication hole (37b) are formed in the partition member.

  • Patent number: 10391431
    Abstract: A strainer device includes a strainer element; a first lid member that covers an upper opening of the strainer element; a second lid member that covers a lower opening of the strainer element and has a fitting hole in a portion surrounded by the strainer element; a delivery pipe protruding upward inside a hydraulic oil tank in a state in which the delivery pipe is fitted into the fitting hole of the second lid member; and a check valve arranged at the first lid member. The check valve includes a valve main body having a valve passage whose one end opens to the internal space of the strainer element and whose other end opens to inside of the hydraulic oil tank; and a valve body which is arranged to be able to move in a vertical direction with respect to a valve seat provided in the valve passage.
