摘要： Multiport pumps and associated pumping systems are described that provide a selective hydraulic or electrically powered pump/pump system. The pumps provide movement within a device or larger system. Movement can cause compression/expansion of a fluid and provide fluid movement within the same device or system. In this instance, the volume of fluid and the fluid flow path within, from, and to the pump(s) is kept constant to reduce or eliminate cavitation, seizure, and/or hydraulic lock. Use of at least one reservoir comprising; a compensator tank, a port allowing for operation at ambient pressure, and a pressure measuring device measuring pressure allowing for unbalanced flow to and from the multiport pumps along with thermal expansion or compression is detailed. In addition, use of a multiport swashplate pumps and associated valve plates that incorporate the features and functions of several valves not heretofore provided within the pump itself is also described.

摘要： A hydrostatic actuator system includes an electric motor for delivering a hydraulic fluid via a piston unit. The actuator system is operating using a method in which a change in volume caused by a temperature change is sensed by a pressure measurement. The method reliably identifies a state of the transfer of the hydraulic fluid from a planetary roller transmission compartment into the master piston. The pressure measurement is continuously evaluated, and, in the event of a negative signal of the pressure measurement, suction of the hydraulic fluid by a planetary roller transmission lying in the hydraulic fluid between the electric motor and the piston unit into the piston unit is recognized and a fault signal is output.

摘要： A passive hydraulic controller is disclosed, in which the volumes V1 and V2 at the two sides of the piston of two or more hydraulic cylinders in each case are connected to one another hydraulically, so that a displacement of the piston in one of the cylinders results in a displacement of the piston in at least one of the other cylinders (follow-up control). The sum of all the piston travels Δs=k1s1+k2s2+ . . . +knsn in hydraulic controllers of said type should ideally always be Δs=0=const, with the proportionality factors k1; k2 . . . kn representing the reciprocal of the piston surfaces of the cylinder, and their signs being dependent on whether the connecting lines between the hydraulic cylinders are crossed or not. Passive hydraulic controllers of the generic type are, however, not positionally stable over time (Δs≠O≠const), in particular under the action of static basic loads. A varying positional error Δs must be taken into consideration, the varying positional error Δs being corrected according to the invention in that in each case when the positional error Δs exceeds a positive positional error limit +Δs which is to be defined, or falls below a negative positional error limit −Δs which is to be defined, a connection is produced between the two volumes V1 und V2 for the purpose of exchanging hydraulic fluid between the two volumes, in that the connection always permits the exchange of hydraulic fluid in only one direction which is determined as a function of the sign of the positional error Δs.

摘要： A damper for use with a hydraulic actuator of the type including a master cylinder and a slave cylinder with a conduit interconnecting the outlet of the master cylinder and the inlet of the slave cylinder. The damper is positioned in the conduit between the master cylinder and the slave cylinder and includes a housing member defining a chamber opening in one face of the housing member and a mounting bracket plate. The mounting bracket plate includes a housing portion corresponding in size and configuration to the one face of the housing member and is positioned against the one face of the housing member to coact with the housing member to seal the chamber. The bracket plate further includes a bracket portion extending outwardly from the housing portion in the form of mounting arms which are utilized to facilitate mounting of the damper to a fixed vehicle structure. A diaphragm is fixedly positioned in the chamber and divides the chamber into a first chamber portion between one side of the diaphragm and the housing member and a second chamber portion between the opposite side of the diaphragm and the housing portion of the bracket plate. This construction enables a single member to function to define the damper diaphragm chamber and further define the mounting bracket to secure the damper within the vehicle.

摘要： An improved compensation piston arrangement for use with a dual circuit master cylinder having a single service piston for simultaneously pressurizing a first fluid chamber and a second fluid chamber, wherein the compensation piston arrangement provides for pressure balancing between the first fluid chamber and the second fluid chamber to compensate for minor normal differences between the first and second fluid chamber. The compensation piston arrangement includes a movable compensation piston slidably disposed within a bore of a compensation housing, wherein the housing defines a pair of end stops positioned on opposing sides of the compensation piston. The bore is in fluid communication with the fluid chambers such that the pressure within the first fluid chamber acts on a first side of the compensation piston, and the pressure within the second fluid chamber acts on a second end of the compensation piston which is opposite the first end. The compensation housing can be incorporated within the service piston or can be remotely located from the master cylinder.

摘要： A double acting hydraulic system including a master cylinder and a slave cylinder. Each of two slave cylinder spaces has a nipple boring (12, 22), for a nipple valve (40, 50), with an internal section in a form of a seat (16, 26) cooperating with an end (41, 51) of the nipple valve. A sealing section (19, 29) in each nipple boring located outside the seat slidingly and sealingly abuts a sealing section (44, 54) of the respective nipple valve. There is an annular space between each nipple valve and nipple boring, between the seat and the sealing section; and a connecting channel (35) provides communication between the annular spaces. One of the nipple valves has a nipple channel (60) with one opening (61) into the corresponding annular space and a second opening (62) to outside the nipple boring; and a device (63) that cooperates with the nipple channel to prevent fluid flow from outside the nipple boring to the annular space.

摘要： A device for the prevention of the abuse of a dry-plate clutch (1) for a motor vehicle with a manual gearbox, wherein the device acts jointly with a hydraulic master cylinder (3) and a related slave cylinder (4) in the operation of the clutch (1). The device comprises a valve unit (20) which is installed hydraulically in series with and between the master cylinder (3) and the slave cylinder (4). The valve unit opens when the valve body (32) is moved towards the slave cylinder (4). A first passage (53) which extends in the valve body (32) or in the valve housing (21) permits restricted fluid flow through the valve (20) when the valve unit (20) is closed. A device (33,35,41) keeps the valve unit (20) open when the clutch is located in positions between a position of maximum disengagement and a second position located close to the position in which the clutch begins to engage. During an engagement of the clutch which is so rapid that there is a risk of damage to the transmission, the force of a spring (40) which attempts to open the valve unit (20) becomes less than the force exercised by the hydraulic fluid on the valve body (32) and attempts to close the valve unit (20), thus causing it to be moved towards its seat (31), whereupon the fluid is forced to flow through the passage (53).
