摘要： The hydraulic machine includes a cam and a cylinder block with pistons co-operating with cam lobes, each of which has two ramps extending between top and bottom dead center arcs. The cylinders are connected in alternation to a feed and to a discharge, in sequences separated by switchover stages including an isolation stage during which they are isolated relative to the feed and discharge main ducts. The angular position of the start or of the end of at least one first isolation stage relative to the corresponding dead center arc is different from the angular position of the start or of the end of at least one second isolation stage relative to its corresponding dead center arc, both of these dead center arcs being top dead center arcs or both of them being bottom dead center arcs.

摘要： A hydraulic system has two hydraulic circuits, each with a pressure generating unit acting on an actuator unit. The generating units are slot-controlled radial piston pumps and form a pump assembly with a single common pump support and single common rotor. The rotor is rotatable on a free protruding section of a common support hub and has piston-receiving bores on axially offset planes. The hub has two first and two second fluid bores. The first bores communicate with first pump connections and first control openings on the hub on a first plane, and the second fluid bores communicate with second pump connections and second control openings on the hub on a second plane. A first and a second adjustment frame, each having an eccentric ring and acting on the pump pistons, are disposed on respective planes perpendicular to the main axis and independently guided in a linearly movable manner.

摘要： A radial piston machine includes a housing, rotor, first braking member, and brake ring with a second braking member. The rotor is mounted in the housing to be rotatable relative to an axis of rotation, and has an end face facing in a direction of the axis of rotation. The first braking member is positioned on the end face. The housing has a body defining a ring-shaped extension relative to the axis of rotation. The brake ring is positioned to surround the extension and is configured to be movable in the direction of the axis of rotation so as to bring the second braking member into braking engagement with the first braking member. The brake ring is further configured to positively engage with an inner radial side of the extension to limit a twisting between the housing and brake ring.

摘要： A Positive Fluid Displacement Device (PFDD) with a removable Fluid Displacement Module (FDM) having two opposing pistons connected to a drive block. The drive block slides over a crankpin bearing in assembly to provide orbital piston motion. Opposing cylinders are held within a carriage for reciprocating motion. An opening in the reciprocating cylinder head allows fluid communication to the displacement chamber through inlet and outlet ports in a floating port plate. The flat surfaces of the port plate and cylinder head wipe across each other during cylinder head movement. The piston head carries a protrusion sized to fill the cylinder head opening. Micro-adjustment mechanisms for the position of the cylinder head together with compliant piston and compliant cylinder mechanisms can provide near zero dead volume. Different sized opposing cylinders enable the delivery of pumped fluids in precise ratios. By connecting the outlet of each cylinder to the inlet of the opposing cylinder, the differential displacement of the two cylinders can be pumped, enabling the delivery of very small quantities of fluid. High vacuum may be delivered by series connection of cylinders. The device may incorporate a dual lip piston seal which is wear compensated over the life of the seal. The PFDD is leakage free and can be driven by stepper motors to deliver a precise fluid amount at low speed even to an exact portion of a piston stroke. A sensor is provided for sensing cylinder head position.

摘要： A hydrostatic radial piston machine 10 is proposed, whose adjustable reciprocating ring 18 has integrated means for detecting the eccentricity 20 between the reciprocating ring 18 and the rotor 14. In combination with the rotating rotor 14 and the binding of the sliding blocks 17 to this reciprocating ring 18, the eccentric location of the reciprocating ring 18 leads to a reciprocating motion of the work pistons 16 in a radial direction. Together with the kinematic conditions in the radial piston machine 10, this leads to a change in the spacing between two successive sliding blocks 17. This change in spacing varies in proportion to the eccentricity 20 of the reciprocating ring 18 and is therefore detected by a measuring instrument. To that end, this measuring instrument has a measured value pickup 27, which is integrated in the reciprocating ring 18 and outputs an increased voltage signal as long as sliding blocks 17, which act as measured value transducers, move past it. The signal course is delivered to an electronic evaluation unit 28 and used by it to determine eccentricity, rotor rpm, and other characteristic variables.

摘要： A radial piston pump with pistons which pump into a circumferential pressure passage has the passage sealed on its outer side by a plastic annular member of a trapezoid-shaped cross-section. The longer parallel side of the cross-section faces radially inwardly and includes a circumferential groove for receiving a resilient O-ring which biases closed pressure valves located between the pistons and the passage. The annular member is adapted to be inserted radially inwardly into the circumferential pressure passage by expanding it and allowing it to contract into the passage. A radially inner side of the circumferential passage is, at a location between two adjacent cylinders, connected to a passage that extends radially inwardly and that is connected to an axial passage that leads to a pressure connection.
