    • PROBLEM TO BE SOLVED: To provide a device capable of smoothly moving a heavy object by very small energy and smooth acceleration and deceleration. SOLUTION: The heavy object is supported by torque of one hydraulic pump/ motor, the heavy object or a counterweight is supported by torque of another hydraulic pump/motor, high pressure ports of both pumps/motors are balanced in states connected to common high pressure piping, and the heavy object is moved up or down by acceleration or deceleration corresponding to a displacement volume change by varying or switching a displacement volume of either one of the pumps/motors in response to a purpose. By the method using gravity, a driving system can be realized theoretically needing no energy and ensuring smooth acceleration and deceleration by an inertia effect based upon gravity.
    • 要解决的问题:提供能够通过非常小的能量和平滑的加速和减速平稳地移动重物体的装置。 解决方案:重物由一个液压泵/电机的扭矩支撑,重物或配重由另一个液压泵/电机的扭矩支撑,两个泵/电机的高压端口在与普通高压连接的状态下平衡 管道,并且重物通过响应于目的改变或切换任一个泵/电动机的排量而对应于排量体积变化的加速或减速而向上或向下移动。 通过使用重力的方法,理论上可以实现驱动系统不需要能量,并且通过基于重力的惯性效应确保平滑的加速和减速。

    • PROBLEM TO BE SOLVED: To provide a rotary type fluid energy conveyor capable of more simply and easily forming a force couple with hydraulic pressure while achieving reduced size and weight, a lower price, a longer life and improved starting torque efficiency by forming the force couple with hydraulic pressure to cancel the bearing load of a radial cylinder type static pressure fluid pump or a motor and eliminate the need for a great capacity rolling bearing. SOLUTION: A static pressure pad 6 held by a casing 5 is provided outside a polygon ring 4 at a position perpendicular to the eccentric direction of a pintle 1. Pressure which is received by a pad-side half-cycle cylinder 21 is introduced into a holding hole 51 to form the force couple with inward force F generated by the slide contact of the static pressure pad with the outer face of the polygon ring and resultant force (an average between Fh3 and Fh4) of outward radial force which is received by the pad-side half-cycle inside plane face of the polygon ring.

    • PROBLEM TO BE SOLVED: To provide a hydraulic rise-and-fall driving system excellent in terms of energy consumption, cost, reliability and structure, and appropriate to be used for ordinary home.
      SOLUTION: This system is provided with a pump/motor PM for a balance weight for supporting the balance weight C suspended by a rope, resisting the gravity, with the torque and a plurality of pumps/motors PM1 and PM2 for supporting a plurality of objects C1 and C2 to be elevated, which are suspended by a rope, resisting the gravity with the torque. In this system, a high-pressure port of each of the pumps/motors PMA and PM2 is connected to a common high-pressure pipe 1, and a swept volume of the pump/motor PM for a balance weight is controlled so that the pressure of the common high-pressure pipe 1 becomes a constant value. On the other hand, in the pumps/motors PM1 and PM2 for objects to be elevated, a swept volume thereof is changed from the condition that the resisting force generated by the torque and the gravity of the objects C1 and C2 to be elevated take a balance with each other to drive rise and fall of the objects C1 and C2 to be elevated with acceleration and deceleration corresponding to a change quantity.
