Description
SPECIFICATION
Spherical Rotary Piston Machine Generating
Variable Volumes
The invention relates to a rotary machine, generating variable volumes, and its mode of operation.
According to the present invention, I provide a "Spherical" rotary machine assembly, including, a mainly longitudinally rotating mainly squat cylindrical rotor and its integral shaft; the said rotor inserted through a angular dispositioned mainly axially synchronously rotating plate; their junction geometrically relatively universally partrotary fit; all housed within and rotating concentrically with the mainly longitudinal axis of a spherical chamber. The whole being optionally complimented by suitable sealing, inlet-exhaust porting, valving, etc.
The formation of the variable individual volumes results from the individual surfaces of mainly longitudinally rotating squat cylindrical rotor relative to the cyclicly continuously varying angle individual surfaces of angular dispositioned mainly axially synchronously rotating plate; both revolving within their own plane, axis concentric with the mainly longitudinal axis of their housing spherical chamber.
The present invention will now be described in greater detail by way of example only; with reference to the accompanying drawings, Sheet 1, Sheet 2, and Sheet 3, wherein:- Figure 1, is a diagram illustrating the arrangement of the squat cylindrical rotor with integral shaft, relative to the rotating plate, (in this selected instance one piece), housed within a ported spherical chamber. The two sets of "crosshatching" indicating individual "Workingchambers" of two "Individual" chambers each.

Figures 4, 5, 6, 7, 8. are sequenced diagrams illustrating views on surface of rotating plate and surface of squat cylindrical rotor at various angular positions, cyclicly varying individual chamber volumes obtained, related to "Fourstroke" principle.

Engine." (Alternatively, as drawn, can be applied as an "Integral Engine Pump.")
Figure 10 is a diagram illustrating a parttransverse plan section of Figure 9. The squat cylindrical rotor with rotating plate rotated through an example 450 rotation.
The principle is illustrated diagramatically in
Figures: 1, lv; 2, 2v; 3, 3v; and 4, 5, 6, 7, 8.
To consider Figure 1, where the curve "a" representing the internal contour of a spherical chamber; in which is inserted a squat cylindrical rotor "b", with its edge surface "c" contoured to sliding-fit spherical chamber contour "a"; and two bearing surfaces "d" combining bearing and pressure loads, selected in this instance as two flat parallel surfaces denoted "d"; its integral shaft "e" locating its longitudinal position.Fitting over squat cylindrical rotor "b", and making a relative "axially universally part-rotary" siiding-fit, its surfaces "w" always in contact with squat cylindrical rotor surfaces "d"; and with pressure surfaces "g" is selected one piece rotating plate "f', which also rotates in spherical chamber "a" at angle a0. The surfaces "g" of rotating plate "f" and surface "d" of squat cylindrical rotor "b", in conjunction with spherical chamber surface a forming an "Individual Chamber" "h". Surface "g" of rotating plate"f" relative to surface "d" of squat cylindrical rotor "b", forming a maximum induced volume; this volume illustrated in Figure 1 v.
Figure 2. illustrating a 900 rotation of squat cylindrical rotor "b" and its integral shaft "e", and corresponding 900 rotation of rotating plate "f"; and the relative "axially universally part-rotary" sliding on surface "d" of squat cylindrical rotor "b", of surface "w" of rotating plate "f', indicated by dimension line "x". As drawn, the position of surface "d" of squat cylindrical rotor "b" relative to surface "g" of rotating plate "f" forming a cyclicly smaller intermediate volume (compared to Figure 1), as illustrated in Figure 2v. The surface "d" of squat cylindrical rotor "b", limited by surface "w" of rotating plate "f", forms a variable positioned area, whose "Centre of Area" or "Centre of Pressure" denoted by symbol "X" at distance "T" from axis of rotation.Angle locating axial rotating position of rotating plate "f', determines dimension "T" relative to squat cylindrical rotor "b" axis of rotation; and also determines "Ratio" of pressure acting as a "Torque" on surface "d" of squat cylindrical rotor "b", by pressure, acting proportionately at "T" on each side of squat cylindrical rotor "b" axis of rotation; and also determines "Compression
Ratio".
Figure 3 illustrating a 1 800, rotation of squat cylindrical rotor "b", and its integral shaft "e"; and corresponding 1 800 rotation of rotating plate "f".
This further rotation is compared to Figure 2, when 900 rotation of squat cylindrical rotor "b" cyclicly compresses volume described in Figure 2.
and Figure 2v; thus surface "d" of squat cylindrical rotor "b" is rotating through 900 whilst relative "axially universally part-rotary" sliding fit in rotating plate "f' which is also rotating through 900. This relative movement of surface "d" of squate cylindrical rotor "b" to surface "g" of rotating plate "f' produces a constantly cyclic varying reducion in volume, until at position illustrated (i.e. 1 800 rotation) the minimum volume is obtained. Figure 3v. illustrating the minimum volume determined in Figure 3. Further reduced by indicated excresance "z".
Further rotation of squat cylindrical rotor "b", with corresponding rotation of rotating plate "f', cyclicly enlarged minimum volume of Figure 3, to conditions applicable to Figure 2. The varying pressure on surface "d" of squat cylindrical rotor "b", and varying distance "T" of "Centre of
Pressure" symbol "X" relative to axis of rotation, produces a turning torque obtained from integral shaft "e".
To apply this principle, for example to the basic requirement of an "Internal Combustion Engine", as demonstrated in Figure 9., which is in substance a reproduction of Figure 1.; drawn at start of induction of "fuel-mixture", and read in conjunction with Figures 4, 5, 6, 7, 8.
Figure 9 is a diagram illustrating a form of construction of the invention and a method of sealing. In this example, the invention is applied in the form of an "Internal Combustion Engine". In this instance a squat cylindrical rotor "b" with circular seals "j" and integral shaft "e"; the squat cylindrical rotor "b" inserted between sliding blocks "k", with seals "I", axially relative partrotating on surfaces "d" of squat cylindrical rotor "b". The sliding blocks "k" are located in a fitted slot with seals "n", within rotating plate "f", sliding longitudinally on curved surface "m" of sliding block "k". This selected arrangement gives squat cylindrical rotor "b", relative to rotating plate "f", gas tight sealing; when sealing is universally partrotating about horizontal centre line "H.L.", vertical centre line "V.L.", rotating plate "f" centre line "P.L.". The rotating plate "f' rotating in conjunction with squat cylindrical rotor "b"; and located in groove "o" within spherical chamber "a" casing "p", and sealed by circular seals "q". A working chamber of two Individual chambers "h" are ported by exhaust ports "r" and inlet ports "s" (bottom individual chambers "h", inlet port "s" not shown.) The ports being positioned relative to rotating squat cylindrical rotor "b".
The cycle of "lnduction-Compression-Power
Exhaust", within the individual chamber "h", as illustrated in Figures 4, 5, 6, 7, 8, can be obtained by rotating squat cylindrical rotor "b" from its drawn position of Figure 9 (Figure 4) in direction of rotation shown. The inlet port "s" being open inducing fuel-mixture, until at maximum volume inlet ports "s" closes when squat cylindrical rotor "b" rotates to 1 800. (Figure 5) Position. The squat cylindrical rotor "b" further rotates through 1800 (Figure 6, 3600) to position as drawn in
Figure 9. The obtained maximum volume of induced fuel-mixture being compressed between surfaces "m" of sliding block "k" with surface "g" of rotating plate "f'; and surface "d" of squat cylindrical rotor "b", where mixture is compressed into minimum volume "u" adjacent to closed exhaust port "r".At this stage compressed fuelmixture is ignited, applying torque to squat cylindrical rotor "b" until at position 1800 (Figure 7, 5400) exhaust valve "r" is open, while further rotation of 1800 (Figure 8, 7200) squat cylindrical rotor "b" scavnges, and is again positioned as drawn in Figure 9 (Figure 4).
By positioning inlet/exhaust porting, and inlet/exhaust valve timing and using both surfaces "d" of squat cylindrical rotor "b", a working chamber of two individual chambers "h" will produce double power or effort to that previously described. Both working chambers can operate at the same time. Thus giving four power of effort operations.
The circular'seals "j", "q", and seals "I", "n", etc., can be duplicated to improve sealing efficiency.
To relieve squat cylindrical rotor "b" of any excessive bending movement, an auxiliary integral shaft "v" denoted by "chain-dot" line, can be fitted radially opposite integral shaft "e"; and could also drive rotating plate "f", inlet-exhaust valving, ignition, etc.
The squat cylindrical rotor "b" can be optionally mounted by one surface "d" to an integral shaft, the two centre-lines making an obtuse angle; when rotating giving a circular loci to adjacent edge surface "c" of squat cylindrical rotor "b". This clearance obtained will enable extra pressure seals "j" to be thereon inserted.
Will necessitate sealing rotating integral shafts (not drawn).
A method of varying "Compression-Ratio" can be obtained by altering angle crO of rotating plate "f". This angle aO alteration can be applied externally, from an external source, through a modified working chamber internal spherical surface "a" (not drawn).
A method of decreasing minimum volume, with small decrease in maximum volume, can be obtained by an excresance "z" applied to outer area of surface "d" of squat cylindrical rotor "b"; or, excresance "z" applied to outer area of surface "g" of rotating plate "f". Ensuring clearances are maintained when rotating.
All valving, porting, rotating plates, etc., their positioning and sequencing is determined by position of squat cylindrical rotor "b".
Alternative methods of valving, porting; such as poppet, slide, rotary valves, masked porting,
etc., can be used to obtain conditions required for
"FourStroke", 'Two-Stroke", "Compression
Ignition" principles, etc. (not drawn).
For application as an "Integral engine-pump", one individual chamber can operate as an "I.C.E."; the other individual chambers as fluid, gas, vacuum pump, etc; with valving, porting, etc., to suit.
For application as a "Fluid-gas motor":
pressurised fluid, gas, can be applied to inlet
positions; thus rotating squat cylindrical rotor, and
rotary power obtained from integral shaft; valving, porting, etc. to suit.
For application as a "Complete fluid-gas
Pump"; rotary power is applied to integral shaft; valving, porting, etc. to suit.
