Abstract:
A single-ended swash plate compressor comprising:a cylinder assembly, which comprises a swash plate chamber internally disposed therein and a plurality of pairs of cylinder bores formed in the front end and the rear end of said swash plate chamber, respectively, the pluralities of cylinder bores at the respective of said ends of said swash plate chamber constituting respective sets of cylinder bores;a rotatable drive shaft centrally disposed in said cylinder assembly;a corresponding plurality of piston assemblies each comprising respective pistons formed on both ends of respective piston rods and which are housed respectively in said pairs of cylinder bores;a swash plate housed in said swash plate chamber which rotates together with said drive shaft to cause said piston assemblies to reciprocate within said cylinder bores;and housing means covering both ends of said cylinder assembly;wherein said pistons in one set of cylinder bores are guide pistons and said pistons in the other set of cylinder bores are compression pistons, the insides of said other set of cylinder bores being connected to an intake side of said compressor by means of intake valves and to a discharge side of said compressor by means of discharge valves,characterized in that a side clearance between each of said guide pistons and a corresponding one of said cylinder bores in said one set of cylinder bores is larger than a side clearance between each of said compression pistons and a corresponding one of said cylinder bores in said other set of cylinder bores.
