Unless you are more than 110 years old, the Brits who built the Australian
pump can probably establish prior art. I think that, using the normal
meaning of the word, the still working Australian water pump may be
considered to have NO moving parts :-).
Worth a look for any old-technology enthusiasts (and would be patent voiders
;-) ).

Excellent diagrams, photos and full description of operation. No moving
parts apart from exhaust and fuel, air & water inlet valves. No water
exhaust valve needed.
As it is more efficient than a steam engine the principle may still have
some practical use as an ultra-simple water pump. The capital cost for a
given power level is probably well below that for an IC engine pump set. Not
much use for rockets though :-)

The Humphrey Pump, was invented by Mr. H.A. Humphrey, eminent Gas Engineer
and Chemist. Born in London in 1868 and educated at Finsbury Technical
College and the Central Institution of the City Guilds, Kensington, England,
he died in 1951 at Cape Province, South Africa.
His pump is an internal combustion pump in which the force exerted by the
explosion of a mixture of flammable gas and air acts directly on the surface
of the water, forcing it to an elevated position.
The aim of Mr. Humphrey was "to produce a pump of great simplicity and
strength of construction in which the explosive force is exerted directly on
the water and in which no rotating flywheel, solid piston, rotating crank,
connecting rod, bearings or glands of any sort are required".
