Description

    BACKGROUND OF THE INVENTION
  • This application relates to a screw compressor, wherein a divider separates the output of two discharge chambers, and wherein a bearing cover is formed integrally with a discharge case which provides the divider wall.
  • Screw compressors are known, and typically include a plurality of rotating rotors each having external screw thread. The screw threads interfit with screw threads on the other rotors to define compression chambers. An entrapped fluid is compressed, and delivered toward a downstream location. One known type of screw compressor includes three rotors, and defines two compression chambers. These two compression chambers have typically delivered compressed fluid into a common discharge plenum. The discharge of fluid into a common chamber can be somewhat out of phase, and can result in increased pulsation and undesirable losses and noise.
  • Thus, it is known in the prior art to provide a divider wall that separates an output from the two chambers until they reach a downstream location. Typically, an outlet housing includes two distinct flow passages. The outlet housing is connected to a discharge case which includes a divider wall to define the two flow passages.
  • In addition, a bearing cover has typically been provided to cover bearings mounted in the outlet housing for each of the three rotors. In the prior art, such as US 6 976 833 B2 , and in US 2006/0065478 A1 , the bearing cover is formed separately from the discharge case. A space between the divider wall and bearing cover has allowed cross flow between the two passages.
    • SUMMARY OF THE INVENTION
  • The invention provides a compressor as defined in claim 1.
  • In the disclosed embodiment, a screw compressor is formed with three rotors. Each of the three rotors has shafts which are mounted in bearings. The bearings are fixed within an outlet housing. The outlet housing is fixed to a compressor case. A bearing cover is formed integrally with a discharge case, as is a divider wall. The outlet housing provides two separate discharge passages which communicate with two separate compression chambers. The two separate discharge passages allow fluid to flow downstream into two separate plenum chambers or flow passages. The separate plenum chambers are defined by the divider wall and the integral bearing cover in the discharge case. Since the bearing cover and the discharge case are formed as integral parts, there are no complex surfaces which must be sealed between the two and no leakage between the plenum chambers. In a sense, the bearing cover forms a part of the divider wall.
  • These and other features can be best understood from the following specification and drawings, the following of which is a brief description.
    • BRIEF DESCRIPTION OF THE DRAWINGS
    • Figure 1 is an exploded view of a prior art compressor.
    • Figure 2 shows the bearing cover feature of the prior art compressor.
    • Figure 3 is an end view of an integral cover and compressor discharge case.
    • Figure 4 is a perspective view of one side of the inventive compressor component.
    • Figure 5 is a perspective view from the opposed side of the inventive compressor component.
    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • A compressor 20, as known in the prior art, is illustrated in Figure 1. A compressor case 22 carries screw rotors 24, 26 and 28. As known, the screw rotors have threads which interfit to compress and drive a refrigerant toward a discharge chamber 38. Refrigerant enters at an opposed end through an inlet 140. The rotors 24, 26, and 28 all have shafts 30 which are mounted within bearing assemblies 32. The bearing assemblies 32 extend into chambers 34 in a outlet housing 36.
  • The outlet housing 36 includes passages 40 which communicate with the discharge chambers 38 and serve to deliver the compressed fluid downstream without allowing fluid from the two chambers 38 to cross flow.
  • A discharge case 46 includes chambers 50 which communicate with the passages 40. A divider wall 48 divides the two chambers 50, such that the compressed fluid will not mix until downstream of the discharge case 46. However, the divider wall 48 and the bearing cover 42 have generally not been on the same plane at the end of the outlet housing 36. Thus, a space has existed between the two separate parts, which has allowed leakage. Figure 2 shows the prior art cover 42.
  • Figure 3 shows an inventive discharge case 100. As shown, a divider wall 102 still divides and separates the chambers 104. However, the bearing cover 106 is formed integrally with this wall 102.
  • Thus, as shown in Figure 4, the bearing cover 106 merges into the divider wall 102. There is no leakage between the wall 102 and the cover 106 as they are formed integrally. The two chambers 104 are thus maintained separate by the relatively simple formation of the integral component. In a sense, the bearing cover forms a portion of the wall.
  • Figure 5 is a perspective view of the opposed side, and shows the chambers 104 separated by the wall 102. As can be appreciated from the several figures, the divider wall 102 is relatively thin compared to the bearing cover 106. The divider wall 102 also extends over the majority of the axial length of the discharge case 100. Adjacent an end of the discharge case 100 which abuts the outlet housing 20, the discharge divider wall 102 merges to be thicker, and provide the bearing cover 106.
  • Although a preferred embodiment of this invention has been disclosed, a worker of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention. For that reason the following claims should be studied to determine the true scope and content of this invention.
