[0001] This patent claims priority from and incorporates by reference the provisional U.S. patent application Ser. No. 60/646825, filed Jan. 25, 2005. BACKGROUND OF THE INVENTION [0002] The present invention relates to the field of valves, more specifically to the field of reed valves. U.S. Pat. Nos. 6,454,545 B1 (Ikeda, 2002), 6,231,315 B1 (Ikeda, 2001), 5,454,397 (Miszczak, 1995), 5,355,910 (Gies, 1994), 5,226,796 (Okamoto, 1993), 5,186,475 (Kawai, 1993), 4,714,416 (Sano, 1987), 4,696,263 (Boyesen, 1987), 4,580,604 (Kawaguchi, 1986), 3,994,319 (Airhart, 1976), 3,983,900 (Airhart, 1976), 3,939,876 (Lundvik, 1976), 2,906,281 (Pillote, 1959), 2,881,795 (Waldenmaier, 1959), 2,864,394 (Hempel, 1958), and 2,476,320 (Paulus, 1949) disclose various valves comprising various cantilever or reed components. None of the cited patents disclose or claim the apparatus of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0003] The structure and operation of the invention will become apparent upon reading the following detailed description of the preferred embodiment and upon reference to the accompanying drawings in which like details are labeled with like identification numbers throughout. The drawings do not conform to a consistent scale. [0004] FIG. 1 is a cross sectional view of an air-conditioning compressor in which the preferred embodiment of the present invention bulkhead insert and reed stabilizer are installed. [0005] FIG. 2 is a cross-sectional view of the front bulkhead of a state-of-the-art air-conditioning compressor that does not embody the present invention. [0006] FIG. 3 is a cross-sectional view of the front bulkhead of the compressor of FIG. 1 in which the preferred embodiment of the present invention bulkhead insert and reed stabilizer are installed. [0007] FIG. 4 is a cross-sectional view of the preferred embodiment of the present invention bulkhead insert. [0008] FIG. 5 is an isometric view of the cantilever portions of a reed valve, its integrated annular support structure, and two integrated tabs with alignment holes. The entire FIG. 5 structure is herein referred to as a "reed." [0009] FIG. 6 is a plan view of a reed retainer. [0010] FIG. 7 is a sectional view of one of the curved radial arms of a reed retainer. [0011] FIG. 8 is a plan view of a gasket. [0012] FIG. 9 is a plan view of a valve plate. [0013] FIG. 10 is a plan view of a suction reed. [0014] FIG. 11 is a cross-sectional view of a cylinder block assembly. [0015] FIG. 12 is a plan view of a shaft. [0016] FIG. 13 is an isometric view of a shaft, two valve plates, a gasket, a suction reed, a discharge reed, a discharge reed retainer, a piston, four alignment pins, and the preferred embodiment of the present invention bulkhead insert. [0017] FIG. 14 is a rotated view of FIG. 13. [0018] FIG. 15 is a cross-sectional view of a reed stabilizer. [0019] FIG. 16 is a large-scale view of the front bulkhead area of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0020] The inventors present herein the best mode for carrying out the present invention in terms of its preferred embodiment, depicted within the aforementioned drawings. Herein, the preferred embodiment of the present invention will be considered to have a front end and a rear end. The end of the preferred embodiment where splined end 25 of shaft 12 in FIGS. 1 and 12 protrudes from front bulkhead 2 will be referred to as the "front," and the opposite end will be referred to as the "rear." "Outboard" herein refers to the direction radially outward from the longitudinal axis of shaft 12. [0021] A reed valve is a valve having a cantilever that is anchored, pinned, clamped, or otherwise held at one end, with the opposite end free to undergo displacement in the process of opening and closing a port or ports that provide ingress or egress of gases, fluids, and substances that have some fluidic characteristics including, but not limited to, grain, sand, and pellets. As is common in the many industries that employ valves, "reed" is used herein to denote the cantilever portion of a reed valve. Although it can be used in any application calling for a reed valve, the preferred embodiment of the present invention is incorporated in an air-conditioning compressor commonly understood in the automotive industry.
