Abstract
An oil supplying apparatus for an opposed type reciprocating compressor comprises oil kickers which are mounted on spring supporting plates coupled to armatures of respective reciprocating motors, or oil valves which are mounted on oil paths formed on a cylinder and communicated with a suction path, and thereby, oil in a casing can be supplied to a slant portion between the cylinder and pistons regardless of the installation type of the compressor. In addition, lack of oil in the compressor and dried friction caused by the lack of oil can be prevented in advance, and a reliability of the compressor can be improved.
Claims19
An oil supplying apparatus for an opposed type reciprocating compressor comprising:
- a casing having a suction pipe and a discharge pipe on both sides thereof to be communicated and having a predetermined amount of oil filled therein;
- a plurality of reciprocating motors installed on inner both sides of the casing to perform reciprocating movements toward opposite directions of each other;
- a cylinder having a compression space mounted between the reciprocating motors;
- a plurality of pistons respectively coupled to armatures of the reciprocating motors and inserted as sliding into the cylinder so that front end surfaces thereof face each other;
- a discharge valve assembly and a suction valve assembly for opening/closing a suction side and a discharge side of the compression space alternately so that the compression space of the cylinder can be communicated with the suction pipe and the discharge pipe alternately;
- spring supporting plates coupled to the armatures of the reciprocating motors;
- and
- oil kickers coupled to outer circumferential surfaces of the spring supporting plates for kicking the oil filled inside the casing during the reciprocating movements.
The apparatus of claim 2, wherein the cylinder includes at least one or more oil holes for inducing and recalling the oil formed respectively on both sides of a through hole through which the pistons are inserted.
An oil supplying apparatus for an opposed type reciprocating compressor comprising:
- a casing having a suction pipe and a discharge pipe which are communicated with each other on both sides thereof and having a predetermined amount of oil filled therein;
- a plurality of reciprocating motors installed on inner both sides of the casing to perform linear reciprocating movements toward opposite directions of each other;
- a cylinder including a compression space mounted between the reciprocating motors;
- a plurality of pistons coupled to armatures of the reciprocating motors and inserted as sliding into the cylinder so that front end surfaces thereof face each other;
- a discharge valve assembly and a suction valve assembly for opening/closing a suction side and a discharge side of the compression space alternately so that the compression space of the cylinder are communicated with the suction pipe and the discharge pipe alternately;
- and
- oil valves mounted on center portions of oil paths, which are formed on inner cross section of the cylinder, for controlling flow of the oil.
