Compressor with pressure limiting

Abstract

A compressor unit in a portable compressed air source, comprising a reciprocating piston compressor which is driven by a slider crank mechanism and has a piston which is moved in reciprocation in a cylinder, said piston delimiting a compression chamber which has a first dead air volume. The cylinder exit is closed off by a cylinder head with an exhaust valve, and the compression chamber can be connected by a valve to at least one other dead air volume.

Description

technical field [0001] The invention relates to a compressor unit in a portable source of compressed air, the compressor unit having a reciprocating piston compressor driven by a slider crank gear (Schubkurbelgetriebe), the reciprocating piston compressor having an internal cylinder A vibratingly moving piston delimits a compression chamber provided with a first air dead volume, wherein the cylinder is closed on the output side by a cylinder head with an outlet valve. Background technique [0002] Such compressor units are for example required with or as part of means for sealing and pumping inflatable objects, especially for sealing and pumping motor vehicle tires (repair kits). [0003] These portable and lightweight units contain a compressor unit as a source of compressed air, in addition, a sealant container for automatic sealant that can be filled into inflatable objects, a container for sealant and compressed air A valve unit and a dispensing unit, and are provided w...

Problems solved by technology

However, a correspondingly designed air dead volume in the compressor reduces its efficiency and requires such unnecessarily large or expensive compressors for achieving the predetermined specifications
