Abstract
A pneumatic device includes a cylinder, a buffer member and a piston unit. The cylinder includes a cylinder wall defining an air chamber. The buffer member has a tubular wall that defines a communicating hole. The tubular wall has a length greater than the wall thickness thereof. The piston unit includes a sealing member, and a rod member movably extending through the communicating hole. The rod member has a driven section received within the air chamber and mounted with the sealing member. The piston unit is movable between a restoring position where the driven section is spaced apart from the buffer member, and an impact position where at least one of the driven section and the sealing member is in contact with the buffer member.
