Problems solved by technology
Most of the traditional closed fuel tanks realize the change of the volume of the fuel tank through the elasticity of the leather bag. Since the leather bag is a rubber product, it is easy to age when it is exposed to the air for a long time, and it is easy to crack and cause leakage if it is continuously raised and sunken. In addition, the connection between the leather bag and the fuel tank The place will lose its elasticity under long-term pressure, and the connection between the bladder and the fuel tank must be processed by a special process, which is not easy to process and manufacture

The invention discloses a volume-variable oil tank for an electrical hydrostatic actuator and belongs to the technical field of electrical hydrostatic actuators. The volume-variable oil tank comprises a tank body, and the tank body comprises an oil tank case with one end being fixedly connected with a dustproof cover and the other end in sealed connection with an oil path block. An oil-gas separation device in sliding and sealed connection with the oil tank case is arranged in the tank body. The oil-gas separation device slides along the oil tank case under action of positive pressure or negative pressure generated by oil. An oil pump is arranged on the oil path block and in an oil cavity formed by the oil-gas separation device, the oil tank case and the oil path block, and the oil pump communicates with the oil path block. An air cavity formed by the oil-gas separation device, the oil tank case and the dustproof cover communicates with atmosphere through a vent hole in the dustproof cover. The oil-gas separation device divides the oil tank into the oil cavity and the air cavity, and slides along the oil tank case under the action of the positive pressure or negative pressure generated by the oil, so that the volume of the oil cavity varies conveniently, the structure is simple, and manufacturing is convenient.
Description
technical field [0001] The invention relates to the technical field of electric hydrostatic actuators, in particular to a variable volume oil tank for electric hydrostatic actuators. Background technique [0002] The electric hydrostatic actuator is an integrated hydraulic system, which integrates and miniaturizes the motor, hydraulic pump, fuel tank, actuator, detection element and controller, making the new integrated integrated actuation system small in size and low in weight. Light, high performance, can realize all the functions of the traditional hydraulic system, and overcome some inherent shortcomings of the traditional hydraulic system, has great theoretical significance and practical value. It has a unique quick-plug and quick-use function. Because of its easy installation, it is only equivalent to installing an oil cylinder, and then connecting the cable to the power supply and controller, and the electric hydrostatic actuator can work. It avoids the cumbersome p...
