Publication number: 20230193885Abstract: A hydraulic machine has a first assembly and a second assembly movable in rotation relative to each other along an axis of rotation. The hydraulic machine has a crankcase defining an internal volume, in which an interface between the fixed assembly and the movable assembly has a housing provided with a first sealing element ensuring the sealing of the internal volume relative to the external environment. A second sealing element is positioned between the internal volume and the housing. The second sealing element is adapted to allow a passage of fluid from the internal volume to the housing when the pressure deviation between the internal volume and the housing is less than or equal to a threshold value, and to isolate the housing from the internal volume when the pressure deviation is greater than the threshold value.Type: ApplicationFiled: May 10, 2021Publication date: June 22, 2023Applicant: Poclain Hydraulics IndustrieInventors: Julien Engrand, Gilles Grillon, Stéphane Quertelet

Patent number: 8177172Abstract: A cable raceway of this kind consists of lengths of wire-type cable raceway comprising both essentially rectilinear lengthwise or weft wires (2) and polygonal-shaped transverse or warp wires (4), with an opening formed in a corner and an even number of sides. Each length comprises at least four lengthwise weft wires (2) supported by at least four separate sides (6, 8, 10, 12) of the transverse or warp wires. For each lengthwise weft wire (2) there is a lengthwise weft wire (2) on the opposite side. The two corresponding lengthwise or weft wires (2) are located opposite each other, that is to say they are both in the same plane and the plane is approximately parallel to one of the lengthwise faces of the cable raceway.Type: GrantFiled: December 8, 2006Date of Patent: May 15, 2012Assignee: I.C.
