Compressor system with a deformable cylinder main body for a puncture repair kit and method for sealing a vehicle tire with such a compressor system

Abstract

A compressor system for a puncture repair kit, in which a supply pressure of compressed air is controlled to a specified pressure Pp or less without the use of a relief valve, having a motor, a piston, which is driven by the motor via a crank mechanism and has a cylinder component with a cylinder main body having a pump chamber, in which a piston is movable between a bottom dead center and a top dead center and air is compressed, and a receiving chamber for receiving the compressed air compressed in the pump chamber through an air discharge valve. The cylinder main body is elastically deformable as the pressure increases, the cylinder main body being deformable to such an extent that the compression volume V2 of the cylinder fulfills the following expression (a) 0.3×V1×P0/(PP−P0)=<V2<0.8×V1×P0/(PP−P0) (a), where V1 is a swept volume which is a cylinder volume while the piston moves from the bottom dead center to the top dead center, V2 is a compression volume which is a cylinder volume when the piston is located at the top dead center, and P0 is an air pressure.
