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 coonnecting 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 friction caused by the lack of oil can be prevented in advance, and a reliability of the compressor can be improved.
Claims21
An oil supplying apparatus for an opposed type reciprocating compressor comprising:
- a casing having a suction inlet and a discharge outlet on sides thereof, said casing containing a predetermined amount of oil;
- a plurality of reciprocating motors installed inside said casing to perform reciprocating movements toward opposite directions of each other;
- a cylinder having a compression space said cylinder being located between the reciprocating motors;
- a plurality of pistons respectively coupled to armatures of the reciprocating motors and inserted slidingly into the cylinder so that front end surfaces of said pistons 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 connected with the suction inlet and the discharge outlet alternately said discharge valve assembly and said suction valve assembly each directly facing a side portion of the compression space;
- 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 inside the casing during the reciprocating movements.

An oil supplying apparatus for an opposed type reciprocating compressor comprising:
- a casing having a suction inlet and a discharge outlet on sides thereof, said casing containing a predetermined amount of oil;
- a plurality of reciprocating motors installed inside said casing to perform linear reciprocating movements toward opposite directions of each other;
- a cylinder including a compression space between the reciprocating motors;
- a plurality of pistons coupled to armatures of the reciprocating motors and inserted slidingly 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 is connected with the suction inlet and the discharge outlet alternately said discharge valve assembly and said suction valve assembly each directly facing a side portion of the compression space;
- and
- oil valves mounted on center portions of oil paths, which are formed on inner cross-sections of the cylinder, for controlling flow of the oil.
