Fuel gas actuator

Abstract

The invention relates to a fuel gas actuator. The fuel gas actuator comprises a cylinder barrel and a piston arranged in the cylinder barrel, wherein a hollow piston rod is fixed on the lower side ofthe piston in a sealed manner, the lower end of the piston rod stretches out of the cylinder barrel and is sealed and fixed with a blocking plate, and a fuel gas generator is arranged in the piston rod; the fuel gas generator comprises a container, gunpowder and an igniter, the gunpowder and the igniter are arranged in the container, the container is of a tubular structure with a closed upper end,the lower end of the container is fixed on the blocking plate, the circumferential wall of the container is provided with a plurality of air ventilation holes, and the igniter is located on the lowerside of the gunpowder and connected with an electric wire drawn from the blocking plate; and the piston is provided with a discharge hole, and an inner cavity of the cylinder barrel communicates withan inner cavity of the piston rod through the discharge hole. The fuel gas actuator has the advantages of being simple in structure, low in cost, high in integration level, small in size and light, can meet the application demands of small space, large loads and single use, and can effectively reduce the cost.

Description

technical field [0001] The invention relates to a gas propulsion device, in particular to an actuator based on high-pressure gas for work. Background technique [0002] The cylinder is a pneumatic component that uses the principle of pneumatic transmission, and the high-pressure gas charged into the cylinder pushes the piston to move along the cylinder, thereby converting the pressure energy of the high-pressure gas into mechanical energy. Cylinders are divided into single-acting cylinders, double-acting cylinders, impact cylinders, rodless cylinders and other types, which are widely used in various fields. Form the air supply system. As a type of cylinder, the impact cylinder requires high air source pressure and large air flow, resulting in a large volume of the entire system and complicated control. For application scenarios with small space and large loads, it is difficult to meet the use requirements; And for the high-value application scenarios of single use, based o...
