摘要： In a positive-displacement hydraulic motor a valve is mounted so as to be moved positively, individually and continuously during the operation of the hydraulic motor. Spacings between adjacent pairs of valve ports, variable volume chambers and cam portions of the guide element are selected from a predetermined relationships. Such an arrangement makes it possible to predetermine the mode of operation for the hydraulic motor by selecting previously the speed of the movement of the valve.

摘要： In an apparatus for controlling the operation of hydraulic motors having infinitely adjustable eccentricity, wherein a flow-control valve between a pump and a hydraulic motor supplied with pressure medium and a control valve for adjusting the eccentricity of the hydraulic motor as a function of the operating pressure required by the hydraulic motor are provided, in connection with pressure optimization for keeping constant the torque of the hydraulic motor, the hydraulic motor is provided with a regulating device (7,10) which is mechanically connected to the eccentric (3) and transmits an eccentric adjustment outward, wherein this mechanical regulating device (7,10) acts on the flow-control valve (17) in such a way that, as a function of the change in the eccentricity, the flow-control valve (17) controls the pressure-medium quantity supplied to the hydraulic motor in such a way that the speed of the hydraulic motor is kept constant.

摘要： This invention relates to steelworks installations provided with an ingot truck drawn by a cable. The invention relates to the system for controlling the cable-tensioning carriage. It is characterized in that the said system comprises a hydraulic jack whose two elements, i.e. cylinder and piston, are respectively connected to a fixed part of the installation and attached to the tensioning carriage, one of the jack chambers communicating with a pressure circuit while the other chamber communicates with a liquid tank via two conduits each containing a valve which opens completely to supply the corresponding chamber and closes partially to allow liquid to escape from said chamber, means for limiting the rate of flow being provided for such escape. This system eliminates any danger of cable oscillation.

摘要： A slave system for a pair of hydraulic cylinders and pistons for retracting one piston while the other piston is extended is provided with valves for venting excess hydraulic fluid when each piston reaches its fully retracted position. The line for the make-up fluid for the slave system is connected to a spool valve in the retracting or rearward end of each cylinder, and when each piston is fully retracted it forces a spool valve open to vent excess make-up fluid and slave fluid. The spool valve is springbiased to a closed position, and when the piston begins to extend the valve closes.

摘要： There is a pressing problem in the design of high-rise apartments and towers during the occurrence of the events like explosion, fire, earthquake since the inhabitants are not able to get out of the building and they get trapped in the dangerous situations.Currently all around the world, there are some systems but they have not met the urgent requirements and we annually witness lots of death tolls caused by fire and explosion.In order to remove the above-mentioned deficiencies, a new system has been designed which creates the possibility of transferring people from heights to the downside of the apartment in emergency conditions without requiring any energy.The device works by converting the potential gravitational power of weight into kinetic and heat energy. This operation is done by controlling and converting the function of a variable and invariable hydraulic pump or hydro motor which is connected to two grooves spool and the pump outlet is controlled by a control valve and centrifugal governor. The control operation causes the spool steel wire to be slowly opened. Consequently the person descends. This system works like a hydrodynamic damper.
