摘要： A hydrostatic transaxle comprises: a housing, an interior space of the housing serving as a fluid sump; an axle supported by the housing; a hydrostatic transmission disposed in the housing so as to drive the axle, the hydrostatic transmission including a hydraulic pump disposed in the housing, a hydraulic motor disposed in the housing, and a center section disposed in the housing, wherein the hydraulic pump and the hydraulic motor are mounted onto the center section, and wherein the center section is formed therein with a fluid circuit for circulation of fluid between the hydraulic pump and the hydraulic motor, and formed with an outwardly opened hole connected to the fluid circuit; a valve holding member fitted into the hole; and a relief valve connected to the fluid circuit through valve holding member. The relief valve is provided with a fixed flow restricting means for passing a specific amount of fluid from a higher-pressurized portion of the fluid circuit to a lower-pressurized portion of the fluid circuit. The relief valve allows fluid after passing through the fixed flow restricting means to flow to the lower-pressurized portion of the fluid circuit when a differential pressure between a primary pressure of fluid before passing through the fixed flow restricting means and a secondary pressure of fluid after passing through the fixed flow restricting means is zero or within a predetermined range.

摘要： The hydraulic linear actuator system of the present invention includes a pump that is configured to rotate in a single direction at a substantially constant velocity. Both the direction and flow rate of fluid through the system is controlled by adjusting the positional relationship between the stator and the rotor of the pump. This positional relationship is adjustable between a forward flow state, a non-flow state and a reverse flow state. The hydraulic linear actuator is responsive to the flow of fluid through the system so as to be displaced in a first direction by the forward flow state of the pump and in a second direction by the reverse flow state of the pump.

摘要： The invention is based on a drive device for a movable part, especially a mold closure device for an injection molding machine. A conventional mold closure device possesses a hydraulic cylinder-and-piston unit having a first hydraulic piston, which borders with a first active surface on a first pressure chamber and with a second active surface, which is smaller than the first active surface and faces in the opposite direction thereto, on a second pressure chamber, and comprises a further hydraulic piston, which is fixedly connected to the first hydraulic piston, and possesses a third active surface, which borders on a third pressure chamber and is active in the same direction as the second active surface. Via a valve arrangement, the second pressure chamber can be connected to the first pressure chamber and can be relieved of pressure separately from the first pressure chamber. In the conventional mold closure device, the cylinder-and-piston unit for closing and opening the mold is operated in open hydraulic circuits, the pressure chambers being connected to a tank at the end of the closure operation and at the end of the opening operation and the movable part evidently being braked only by friction. It is an object of the invention further to develop a drive device of the conventional type so that it can be operated at higher dynamics. This is achieved in that a second hydraulic cylinder-and-piston unit is present, having a second hydraulic piston which is movable relative to the cylinder by a drive motor, especially an electric drive motor, and borders with a fourth active surface on a fourth pressure chamber, which is permanently connected to the third pressure chamber, and with a fifth active surface, which faces in the opposite direction to the fourth active surface, borders on a fifth pressure chamber, which can be connected to the first pressure chamber, and wherein the dimensional relationship between the fifth active surface and the difference between the first active surface and the second active surface is equal to the dimensional relationship between the fourth active surface and the third active surface. In a drive device according to the invention, a pressure which brakes the movable part builds up in the first pressure chamber and in the second pressure chamber or third pressure chamber when the second hydraulic piston is no longer moving, without a valve having to be actuated for that purpose.

摘要： This invention describes a bone lengthening device, which is fully implantable and works on a cylinder and piston basis which is driven with micro-hydraulics or a internal threaded rod. Choosing a profile which is not round, torsion of the cylinder and piston assembly is avoided, and expansion can be achieved both in a linear as well as in a circular fashion. Since this device is fully implantable, common disadvantages with current methods of bone expansion can be eliminated.

摘要： A hydraulic master and slave cylinder assembly of the type in which a piston is positioned in the master cylinder, a piston rod is connected to the piston and extends out of the input end of the master cylinder, a piston is positioned in the slave cylinder, a piston rod is connected to the slave cylinder piston and extends out of the output end of the slave cylinder, a first conduit extends between the output end of the master cylinder and the input end of the slave cylinder, and a second conduit extends between the input end of the master cylinder and the output end of the slave cylinder. The length of the conduit interconnecting the input end of the master cylinder and the output end of the slave cylinder is greater than the length of the other conduit by an amount compensating for the difference in the full bore volumes of cylinders and the piston rod or annular bore volumes of the cylinders so that the total volume defined on the full bore sides of the cylinders, including the interconnecting conduit, is substantially equal to the total volume defined on the annular sides of the cylinders, including the interconnecting conduit, with the result that creep occurring in the system as a result of extreme temperature variations within the system is substantially eliminated so that the assembly may be used as a remote shift mechanism for a motor vehicle automatic transmission without fear of inadvertently shifting the transmission due to creep occurring in the system in extreme temperature situations.
