摘要： Hydrostatische Axialkolbenmaschine, in deren Gehäuse (4) ein Triebwerksraum (2) mit einem Triebwerk angeordnet ist, das über ein Lager (6) in dem Gehäuse (4) gelagert ist, wobei das Lager (6) benachbart zu einer Steuerscheibe des Triebwerks angeordnet ist, wobei an das Gehäuse (4) oder den Triebwerksraum (2) ein Kühlkreislauf zur Kühlung des Triebwerks ausgeschlossen ist, wobei ein Kühlmittel des Kühlkreislaufs gleich einem Arbeitsdruckmittel der Axialkolbenmaschine ist, wobei der Kühlkreislauf eine Kühlmittelpumpe (10) und eine Wärmeabgabevorrichtung (12) hat, und wobei der Kühlkreislauf durch das Lager (6) verläuft. Ein servohydraulischer Aktuator mit einer solchen Axialkolbenmaschine (3) ist ebenfalls offenbart.

摘要： A hydraulic pump (1) includes: a valve plate (6) including a suction port and a delivery port; a valve cover (7) to which the valve plate (6) is mounted; and a cylinder block (2) that slides on the valve plate (6). The valve cover (7) includes a suction passage and a delivery passage. The valve cover (7) includes: a first chamber (8) that communicates with the delivery passage through a communication passage (81) and functions as a Helmholtz resonator; and a second chamber (9) that communicates with the delivery passage, or with the first chamber (8), through an introduction passage (91) including a restrictor (92). In the valve cover (7) and the valve plate (6), a supply passage (93) extends from the second chamber (9) to a bottom dead center-side sealing surface (64) of the valve plate (6), the bottom dead center-side sealing surface (64) being a surface located between the suction port and the delivery port. The supply passage (93) includes a restrictor (94).

摘要： A hydraulic machine comprising a first member (1) having a first structure (2) for a hydraulic medium opening in a first interface surface (3) and a second member having a second structure for the hydraulic medium opening in a second interface surface is described, the first interface surface (3) being in contact with the second interface surface, wherein at least one of the members (1) is provided with a support element (6) surrounding the member (1).
Such a machine should have a good efficiency.
To this end the support element (6) comprises a strength varying in circumferential direction around the member (1) and/or in thickness direction in a middle region of the member (1).
