[0001] This application claims priority to Korean Application No. 10-2005-0129085, filed in Korea on Dec. 23, 2005, the entirety of which is incorporated herein by reference . BACKGROUND OF THE INVENTION [0002] 1. Field [0003] The field relates to a compressor, and more particularly, to a reciprocating compressor. [0004] 2. Background [0005] In general, a compressor converts mechanical energy into compressive energy. Compressors may typically be categorized into a reciprocating type, a scroll type, a centrifugal type and a vane type. Reciprocating compressors may be further categorized into a horizontal type compressor, and a vertical type reciprocating compressor. [0006] Due to the need to provide for lubrication of various components, combined with the placement and orientation of the various components of the horizontal and vertical type reciprocating compressors, additional space is required in the casing to accommodate the oil. Further, in a horizontal type reciprocating compressor, assembly is complicated due to the large number of components of the oil pump, and oil is not smoothly and continuously provided when oil viscosity is high. Likewise, the vertical orientation of the components of a vertical type reciprocating compressor makes it difficult to pump oil to the various components, thus decreasing reliability of the compressor. [0007] Descriptions of reciprocating compressors and operation thereof can be found in, for example, U.S. Pat. Nos. 6,875,000, 6,875,001, and 6,863,506, which are subject to an obligation of assignment to the same entity, and the entirety of which is incorporated herein by reference. BRIEF DESCRIPTION OF THE DRAWINGS [0008] The embodiments will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein: [0009] FIG. 1 is a cross-sectional view of an exemplary vertical type reciprocating compressor having an oil pumping system as embodied and broadly described herein; [0010] FIG. 2 is a cross-sectional view of the exemplary compressor shown in FIG. 1 which illustrates an oil suction process as embodied and broadly described herein; [0011] FIG. 3 is a cross-sectional view of the exemplary compressor shown in FIG. 1 which illustrates an oil supply process as embodied and broadly described herein; [0012] FIG. 4 is a cross-sectional view of another exemplary vertical type reciprocating compressor having an oil pumping system as embodied and broadly described herein; [0013] FIG. 5 is a cross-sectional view of another exemplary vertical type reciprocating compressor having an oil pumping system as embodied and broadly described herein; and [0014] FIGS. 6-8 are exemplary installations of the exemplary compressors shown in FIGS. 1, 4 and 5. DETAILED DESCRIPTION [0015] A reciprocating compressor having an oil pumping system in accordance with embodiments as broadly described herein is shown in FIG. 1. Although a reciprocating compressor, and particularly a horizontal type reciprocating compressor, is presented for ease of discussion, it is well understood that an oil pumping assembly as embodied and broadly described herein may be applied to other types of compressors and/or other applications which require fluid pumping as described herein. The exemplary reciprocating compressor includes a casing 100, a suction pipe SP and a discharge pipe DP extending through the casing 100, a reciprocating motor 200 installed in the casing 100 and having a linearly-reciprocating mover 230, and a compression unit 300 which compresses fluid as a piston 320 coupled to the mover 230 of the reciprocating motor 200 reciprocates with the mover 230. [0016] The reciprocating motor 200 may include an outer stator 210 having a winding coil 211 thereon, an inner stator 220 installed in the outer stator 210 with a certain gap therebetween, and a mover 230 having a magnet 231 positioned in an air gap between the outer stator 210 and the inner stator 220. [0017] The outer stator 210 is supported by first and second fixed frames 240 and 250 coupled to opposite ends of the mover 230 by, for example, a bolt or other suitable fastener, and is fixedly coupled to the casing 100. The inner stator 220 may be pressed-fit to an outer circumferential surface of the first fixed frame 240. [0018] In certain embodiments, the first fixed frame 240 has a disc shape with an outer diameter similar to that of the outer stator 220, with a cylindrical fixing protrusion 241 which extends in a backward direction. The inner stator 220 is installed onto an outer circumferential surface of the first fixed frame 240, and a cylinder 310 is inserted into an inner circumferential surface of the first fixed frame 240. [0019] An oil storage portion 242 for receiving oil at the time of assembling the compressor may be formed in the compressor. In the exemplary compressor shown in FIG. 1, the oil storage portion 242 is formed in a ring shape at an inner side surface of the first fixed frame 240. Other locations and shapes may also be appropriate. An oil passing hole 243 may be formed, for example, at the fixing protrusion 241 of the first fixed frame 240 so as to be connected to an oil pocket 323 formed between the cylinder 310 and the piston 320. [0020] The mover 230 may be coupled to an outer circumferential surface of a movable frame 232 on which a plurality of magnets 231 is arranged between the outer stator 210 and the inner stator 220. The movable frame 232 may be formed in, for example, a cylindrical shape having two opened sides. A rear side of the two opened sides has portions which extend inward towards the center so as to be coupled to the piston 320 of the compression unit 300 by, for example, a bolt or other suitable fastener. [0021] The compression unit 300 may include a cylinder 310 inserted into and fixed to the fixing protrusion 241, a piston 320 coupled to the mover so as to reciprocate in a compression space 311 of the cylinder 310, a plurality of resonance springs 330 and 340 which elastically support forward and rear sides of the piston 320, a suction valve 350 provided at an end surface of the piston 320 so as to open and close a suction channel 321a of the piston 320, thereby regulating suction of fluid as necessary, a discharge valve 360 mounted at a discharge side of the cylinder 310 which opens and closes the compression space 311, thereby regulating discharge of fluid, a valve spring 370 which elastically supports the discharge valve 360, and a discharge cover 380 which covers a discharge side of the cylinder 310, and in which the discharge valve 360 and the valve spring 370 are received. The discharge cover 380 is inserted into a cover insertion hole 110 provided at an appropriate side of the casing 100. Continue reading about Reciprocating compressor...
