    摘要: Dispositif (10) pour diviser ou réunir un débit de fluide comprenant un carter qui présente au moins un orifice primaire (OP) et des orifices secondaires (OS4) susceptibles d'être respectivement traversés par un débit primaire de fluide et par des débits secondaires de fluide. Le dispositif comprend un bloc-cylindres (14) présentant une pluralité de cylindres radiaux (16), et une came de réaction (11) solidaire du carter. Le bloc-cylindres comprend un conduit de cylindre (20) pour chaque cylindre et le dispositif comprend un distributeur de fluide (22), solidaire en rotation du carter et comportant des conduits primaires de distribution (24P) reliés à l'orifice primaire (OP), et des conduits secondaires de distribution (24S) respectivement reliés aux différents orifices secondaires (OS4). Chaque conduit de cylindre (20) est apte, au cours de la rotation relative du bloc-cylindres (14) et du carter, à être alternativement relié à un conduit primaire de distribution (24P) et à un conduit secondaire de distribution (24S).

    摘要: A hydraulic motor includes a motor mechanism that rotates by hydraulic liquid pressure led from a hydraulic liquid pressure source. The hydraulic motor includes a casing that defines a casing chamber which accommodates the motor mechanism, a brake mechanism that brakes the rotation of the motor mechanism, a brake release actuator that releases the braking of the brake mechanism by a brake release pressure led from the hydraulic liquid pressure source, and a throttle passage that is in communication with the casing chamber and extracts a portion of hydraulic liquid that is led into the brake release actuator and leads it to the casing chamber.

    摘要: A fluid pressure pump motor (100, 200, 300, 400) includes a supply/discharge passage (4) where both a hydraulic fluid pumped in to a fluid pressure pump (10) and a hydraulic fluid discharged from the fluid pressure motor (20) flow, and a variable valve (7, 207, 307, 407) provided in the supply/discharge passage (4) to control the fluid path area of the supply/ discharge passage (4). The variable valve (7, 207, 307, 407) reduces the fluid path area of the supply/discharge passage (4) for simultaneously actuating the fluid pressure pump (10) and the fluid pressure motor (20) to be smaller than the fluid path area for actuating only one of the fluid pressure pump (10) and the fluid pressure motor (20).

    摘要: An axial piston machine, in particular an axial piston pump, of the swashplate or bent axis type, is described, wherein a fixed control plate (12), which comprises at least one control passage (12a) consisting of a plurality of control passage sections (12b, 12c) separated from each other by bridges (12d), is arranged between a cylinder drum, rotatable in both directions of rotation, and a fixed housing. The object of the invention is to design the control plate of an axial piston machine in such a way that damage by cavitation to the structural parts is prevented over the entire extent of the control passages for the supply and removal of the operating fluid. For this purpose the at least one control passage (12a) in the region at least of one bridge (12d) is provided with a pressure balance opening (13) connecting the surfaces of the control plate (12) with one another.

    摘要: A hydraulic motor includes a motor mechanism that rotates by hydraulic liquid that is supplied/discharged from a hydraulic liquid pressure source through one of a first motor passage and a second motor passage. The hydraulic motor comprises a casing that defines a casing chamber which accommodates the motor mechanism, and a flushing passage that is in communication with the casing chamber and extracts a portion of the hydraulic liquid from a low pressure side among the first motor passage and the second motor passage and leads it to the casing chamber.

    摘要: A variable displacement hydraulic axial piston machine includes (a) a housing having an outlet opening; (b) a barrel mounted in the housing for rotation about a rotation axis; (c) a plurality of pistons movable in respective bores in the barrel; (d) a valve plate coupled to the barrel and having a fluid passage therein that ends at an outlet opening; and (e) a flow tube connecting the outlet opening in the valve plate to the outlet opening in the housing. The barrel and the valve plate are pivotally movable together about a pivot axis transverse the rotation axis for varying the displacement of the pistons in the bores. An end of the flow tube connects to the valve plate while allowing for axial movement of the flow tube relative to the valve plate in a direction parallel to the rotational axis of the barrel.
