Self-chargeable pneumatic cylinder |
摘要 |
A self-chargeable pneumatic cylinder comprises a cylinder body, a working piston disposed inside the cylinder body, and a hollow elongate shaft coupled to the working piston and extending outward from the cylinder body. The hollow interior of the shaft contains a pump mechanism for charging the pneumatic cylinder with a gas. The pump mechanism comprises a pumping piston that is axially slidable within the interior of the shaft and a pumping rod coupled to the pumping piston that is extendable out of the shaft for facilitating actuation of the pump. As the pump is manually actuated, pressurized gas flows into the cylinder body across a one-way valve to charge the pneumatic cylinder as desired.
