'29-, W y vw w -f" AT TORNEYS SWASII PLATE GAS COMPRESSOR BACKGROUND OF THE INVENTION This invention relates to a swash plate compressor particularly adapted for supplying compressed gas to a gas turbine.
Commercial gas turbines oftentimes utilize natural gas as a fuel. The gas normally requires precompression prior to its delivery to the turbine for efficient combustion purposes. Conventional swash plate compressors oftentimes require very close machining tolerances and the replacement of worn thrust bearing shoes thereof when undue piston end play induces inefficient turbine operation. In addition, the compressed, exhausted gases are generally communicated to the turbine in a non-cooled state and the compressor housing requires extensive machining and related fabrication.
SUMMARY OF THE INVENTION An object of this invention is to overcome the above, briefly described problems by providing a noncomplex, economical, and efficient swash plate compressor comprising means for adjusting its thrust bearing shoes, positioned between each piston and a swash plate, to precisely adjust the pistons to produce equal operating clearances at opposite ends thereof.
In addition, the intake passages to the compression chambers of the compressor are preferably arranged in surrounding heat exchange relationship with respect to the exhaust passages thereof to cool the exhausted, compressed gases prior to their communication to a gas turbine, for example. Also, substantially identical cylinder blocks and heads preferably comprise the compressor housing.
BRIEF DESCRIPTION OF THE DRAWINGS Further objects of this invention will become apparent from the following description and accompanying drawings wherein:
FIG. 1 is a longitudinal, sectional view of a gas compressor taken in the general direction of arrows l--I in FIGS. 3 and 4;
FIG. 2 is another longitudinal, sectional view of the gas compressor, taken in the general direction of arrows II-II in FIGS. 3 and 4;
FIG. 3 is an exploded, isometric view of the gas compressor;
FIG. 4 is a cross sectional view of the gas compressor, taken in the direction of arrows IVIV in FIG. 1; and
FIG. 5 is an enlarged cross sectional view of an oil pump, employed in a lubrication system for the gas compressor, taken in the direction of arrows V-V in FIG. 1.
DETAILED DESCRIPTION Referring to FIGS. 1-3, the housing ofa gas compressor comprises a pair of substantially identical and abutting cylinder blocks 1 1, each having an intake reed plate 12, a spacer plate 13 and an exhaust reed plate 14, mounted on an outboard end thereof. The cylinder blocks and plates are clamped together as a unit, along with substantially identical front and rear cylinder heads 15 and 15', respectively, by 14 double-end rods 16. Since the two halves of the gas compressor are substantially identical, like numerals are used to depict corresponding constructions.
Four cylinder bores 17 are formed in each cylinder block to reciprocally mount pistons 18 therein. As shown in FIG. 1, each axially opposed pair of pistons are interconnected by a bridging connection 19 to be reciprocated simultaneously by a swash plate 20. The swash plate is keyed at 21 to a shaft 22 which may be selectively rotated by a drive input shaft 23.
Each piston has a cup member 24 threadably mounted thereon to adjust the cup member axially between the piston and the swash plate to precisely set the distance between each piston and a respective reed plate 12. A serrated ring 25 is secured to the cup member to provide lock means for positively locking the member in place by its releasable engagement with a cantilevered, resilient spring member 26, secured to the piston. A ball bearing 27 is seated in the cup member and also seats in a bearing shoe or second cup member 28, in slidable contact with the swash plate, to provide drive means for transmitting axial movement from the swash plate to the piston.
It can thus be seen that selective adjustment of each pair of axially opposed cup members 24 will effect equal clearances at the opposite ends of therespective pistons. During operation loads occasioned by rotation of the swash plate are readily counteracted by means of axially spaced collar bearings 29 and thrust bearings 29a.
The natural gas to be pressurized is communicated to an intake manifold 30 via an inlet 31 (FIG. 3) of intake passage means. The gas then flows to annular chambers 32 and through ports 33 and intake reeds 34 into compression chambers 17 (FIG. 2). When the gas pressure exceeds a predetermined level in a chamber, upon the compression stroke 35 of a respective piston, an exhaust reed 36 opens to permit the pressurized gas to exit therefrom and through exhaust passage means. In particular, the pressurized gas then flows through a port 37, formed in spacer plate 13, into an annular chamber 38 and through a passage 39 which communicate with a discharge manifold 40. Outlet 41 of the manifold may be connected to the fuel supply for a gas turbine engine, for example. It should be noted that inlet chambers 32 and ports 33 are disposed in surrounding, heat exchange relationship with outlet chamber 39, and passages 38 for gas cooling purposes.
Referring to FIG. 3, the intake reeds 34 are cut into a plate 12 to be radially disposed about the longitudinal axis of shaft 22. Each reed comprises an inner leg portion 42 connected to a main body thereof and an outer tab portion 43 which seats in a mating, arcuate cutout formed in the intake reed plate to precisely control the opening and closing of the intake reed. The main body portion of the intake reed will normally be urged into masked, sealing relationship with an underlying port 33 prior to its opening upon movement of the piston away therefrom.
The exhaust reeds 36 are also radially disposed about the longitudinal axis of shaft 22 and are cantilevered on an exhaust reed plate 14 to normally mask underlying ports 37. The maximum opening of each exhaust reed is limited by a fixed stop member 44. The stop members are radially disposed on a star-like member secured between the housing and the exhaust reed plate (FIG. 1).
Referring to FIGS. 1 and'5, an oil lubrication system for the compressor comprises an oil sump 45, cast integrally in the cylinder blocks. A line 46 communicates the sump with an oil pump 47 driven by shaft 22. Oil is pumped through a rifle passage 48 formed in the shaft to communicate oil to collar bearings 29 via ports 49 and to thrust bearings 30 and to swash plate 20 via ports 50.
Oil is returned to the sump from the swash plate chamber via slots 51 and from the cylinder heads via passages 52. Lubricating oil temperature is preferably maintained at a suitably low level by means of a recirculated coolant. The coolant is communicated to inlets 53 (FIGS. 1 and 3) and is circulated through passages 54 and to outlets 55.
