  • Publication number: 20190249670
    Abstract: The invention relates to a method of venting a synthetically commutated hydraulic pump (2). The connecting fluid conduits (8, 16), connecting said synthetically commutated hydraulic pump (2) with a fluid reservoir (7) is vented at least on start-up of the synthetically commutated hydraulic pump (2), using a fluid intake device (14, 17, 20) that connects to a fixed displacement pump (3).

  • Patent number: 10359127
    Abstract: The invention to a valve unit (1) for a synthetically commutated fluid working machine (51), comprising a valve body (19,57), a movably arranged valve unit (3) and a separate fluid flow influencing unit (13, 25, 31, 35, 46, 56). The fluid flow influencing unit (13, 25, 31, 35, 46, 56) comprises a fluid flow influencing means part (18) and an attachment means part (28, 34, 38) for mechanical connection with the valve body (19). The attachment means part (28, 34, 38) and the fluid flow influencing unit (18) are connected to each other by a connection means part (27, 30, 33, 40, 47). The circumferential extent of the attachment means part (28, 34, 38) is larger as compared to the circumferential extent of the connection means part (27, 30, 33, 40, 47).
