Claims

[Scope of utility model registration request]

A spring-type air cylinder includes a piston that is slidably disposed within a cylinder tube and defines a head side chamber and a rod side chamber on both sides, respectively, and a piston rod that is fixed to the piston and extends from the rod side chamber side to the outside of the cylinder tube. and,
a spring biasing the piston toward the head side chamber, and the switching valve supplies a high pressure air source and a low pressure air source to the head side chamber and the rod side chamber, respectively, when the piston rod is extended from the cylinder tube. and when the piston rod is drawn into the cylinder tube, the low pressure air source and the high pressure air source are connected to the head side chamber and the rod side chamber, respectively. Tube.
