HYDRAULIC EQUIPMENT |
摘要 |
Hydraulic equipment capable of realizing a same function as a variable displacement pump by controlling hydraulic devices such as control valves in such a state that a hydraulic pump driven by a drive source such as a heat engine or a motor is operated always with a high efficiency and at a general ly constant speed irrespective of the type of the pump, characterized in that a constant pressure hydraulic source is formed by driving the hydraulic pump b y the drive source having, internally or by addition, a specified amount of inertia, peripheral elements according to a load requirement are arranged, a nd the control valves are opened and closed according to the states of the load s including an energy storage device or a hydraulic motor so that hydraulic oi l ranging from a high-pressure small flow to a low-pressure large flow can be fed to the load.
