Infinitely variable pumps and compressors
Infinitely variable motion control (IVMC) provides motion control without any requirement for changing gears or use of a clutch. A spur gear transgear, defined as a system having an input, an output and a control, a variable pitch cam having an eccentric inner and outer cam assembly and a driver may be used to form a speed converter. The speed converter is used in various forms to provide an infinitely variable transmission, a differential, embodiments of wind and river turbines and pumps/compressors. In one embodiment, the speed converter drives first and second directional control assemblies to provide a vehicle with zero turn radius. Various embodiments of an infinitely variable pump or compressor are described.
1. An infinitely variable pump/compressor assembly for driving a reciprocating pump, the infinitely variable pump/compressor assembly comprising
a spur gear transgear assembly with cam control contained within a housing, the infinitely variable pump/compressor assembly having an input shaft for driving one of a pump and a compressor, the cam control having a drive and a control, the control having a control sleeve surrounding a control shaft having first and second inner cams integral with or attached to the control shaft,
first and second reciprocating pistons, each reciprocating piston being driven by an associated piston driver, each reciprocating piston comprising the associated piston driver, a piston arm and a piston,
the control shaft comprising the first and second inner earns, and
first and second outer cams of varying eccentricity, the control shaft driving the pump or compressor.
2. The infinitely variable pump/compressor assembly of claim 1 further comprising a worm control for a worm gear, the worm gear being integral with or attached to the control sleeve surrounding the control shaft, the control sleeve having a left sun gear integral with or attached to the control sleeve and associated with first and second carriers.
3. The infinitely variable pump/compressor assembly of claim 1 , further comprising the control sleeve surrounding the control shaft for controlling eccentricity of the first and second inner cams and the first and second outer cams of the control shaft.
4. The infinitely variable pump/compressor assembly of claim 1 further comprising an output shaft for driving one of a rotary pump and a compressor, the output shaft being coupled to the control shaft and having associated output gears and first and second drivers surrounding the output shaft, the drivers having sprags for one-way rotation of the output shaft driving the rotary pump or compressor.
5. The infinitely variable pump/compressor assembly of claim 1 further comprising a drive gear attached to the input shaft, the drive gear being meshed to first, second and third slotted gears, where the first slotted gear has one slot at the top, the second slotted gear has two slots, one slot at the top and one slot at the bottom, and the third slotted gear has one slot at the bottom.
6. The infinitely variable pump/compressor assembly of claim 4 , the input shaft, the control shaft and the output shaft being housed in a housing, the rotary pump or compressor being external to the housing.
