| PURPOSE: To enable control of a relatively large fluid mass flow with a small structural height by providing a control mechanism having a displacer fluid motor through which the fluid stream flows and an actuating element directly lock or release a displacer element during operation. CONSTITUTION: In a piezoelectric valve, the actual control member 7 placed between an inlet port 3 and an outlet port 4 and the actuating member 8 for the control mechanism 7 are equipped. The control mechanism 7 is equipped with a displacer fluid motor 9 through which the fluid stream 5 flows. The piezoelectric actuating element 8 is disposed in the region of a displacer element 1, which can be moved by the fluid stream 5 and belongs to the displacer fluid motor 9, and can at least directly lock or release the displacer member 1 during operation. Thus a comparatively large fluid stream flow can be controlled by structural height as small as possible. COPYRIGHT: (C)1993,JPO | ||||||

| PURPOSE: To secure min. discharge pressure by furnishing a plunger pump with a piston device connected to a flow line in connection with the discharge port of a gear pump and to a selector valve device in connection with this flow-line. CONSTITUTION: A plunger pump 6 includes a body 6a, a suction flow-line 7 facing the suction port 4b of a gear pump, a flow-line 9 in connection with the discharge port 4c of the gear pump 4, a selector valve 17, a pressure control valve 5 interposed between the flow-line 9 and selector valve 17, and a piston device 25. When current is supplied to a motor 3, the gear pump 4 rotates, and the lubricant under pressurization discharged therefrom passes through the flow line 9 to flow into a selector valve chest 17a and also into a cylinder chamber 24 until the top 26a of the piston 26 contacts the bottom 28a of an adjusting sleeve 28.

| PURPOSE:To eliminate nonconformities in the tight corner braking phenomenon of a part-time four wheel drive vehicle and troublesome manipulation of the latter, by providing a hydraulic control circuit including a hydraulic pressure control means between the discharge port and suction port of a hydraulic port. CONSTITUTION:A four wheel drive coupling device 13 is composed of a vane pump 20 and a hydraulic control circuit 21, and a rotor 20a and a cam ring 20b are integrally rotated through the intermediary of oil under the static pressure of the oil when the discharge port of the pump 20 is blocked. Further, oil passages 26, 27 are communicated with a discharge oil passage 41 through two changeover check valves 31, 32 serving as changeover means, and a relief valve 33 serving as an oil control means is disposed in the discharge oil passage 41. In this device 13 the discharge pressure is controlled to be prevented from exceeding a predetermined value by means of a relief valve 33 and therefore, changeover between the four wheel drive and the two wheel drive is automatically made, and the four wheel drive condition having a drive force in accordance with the differential speed between the front and rear wheels may be obtained. | ||||||

| PURPOSE:To prevent a braking phenomenon in time of a turning drive from occurring, by coupling an axle transmitting driving force to front wheels and another axle transmitting driving force to rear wheels both with a hydraulic pump which is driven by a rotation differential between these axles and discharges an oil quantity commensurate to this rotation differential. CONSTITUTION:In time of a normal straight drive, there is produced no rotation differential between a first axle 11 and a second axle 14 of a coupling device 13 for four-wheel drive use, therefore no hydraulic pressure is produced at a vane pump 20. When speed of rotation largely differs between front and rear wheels 9 and 16 due to various road conditions, a rotation differential is produced between the first axle 11 and the second axle 14 whereby large hydraulic pressure is produced at the vane pump 20. When it exceeds the specified pressure, a relief valve opens and discharge pressure is controlled to make it almost constant. With this hydraulic pressure, it comes into a four-wheel driving state, while brake torque in wheels at the side, where they are rather being locked, is made to grow large, preventing these wheels from locking, thus the rotation differential is made so as to be reduced. | ||||||

| A beverage syrup pump system is disclosed including a pump housing having an internal pumping chamber, a pump motor, and a pumping mechanism driven by the motor within the pumping chamber. The pumping mechanism receives a syrup fluid at a first pressure and discharges the fluid at a second pressure which is greater than the first pressure. A pressure transducer adjacent a sensor port and in contact with a quantity of the fluid at the second pressure generates an electrical signal based upon the second pressure. A programmable micro controller receives the electrical signal from the pressure transducer and is capable of starting and stopping the pump motor. The micro controller will immediately stop the pump motor if the second pressure exceeds a predetermined maximum pressure level. The micro controller will also stop the pump motor if the second pressure falls and remains below a predetermined minimum pressure level for a predetermined first time interval. | ||||||

| A vehicle hydraulic device is provided with an electric motor-driven oil pump and a shuttle valve, so that a vane pump operates smoothly, even at the start, with a backpressure applied from the electric motor-driven oil pump to the vanes. Even when the oil pressure of a working fluid discharged from the vane pump exceeds the backpressure inside vane housing grooves, the working fluid flows from a vane pump discharge oil passage to a backpressure oil passage, so that the vanes are not pushed into the housing grooves. Thus, it is possible to reduce the fluctuations in discharge amount of the vane pump due to fluctuations in oil pressure of the vane pump discharge oil passage during operation of the vane pump. | ||||||
