Robin,
I think before anyone could even make an educated guess, they would have to see
the design and understand the theory of operation of such a device before they
could even begin to consider whether it could be installed on any kind of aircraft.

http://www.rothsport.com/Products/Engine/Oil-Inlet-Check-Valves/Oil-Inlet-Check-Valves.htm
I am wondering if this check valve will work between our tank and engine to reduce the possibility of hydraulic lock? It is designed for Porsche air cool 911 engine which has a dry sump oil system. Here is a description of how this valve works from www.pelicanparts.com:
"One of the common problems with classic 911s can be a plume of oil smoke from
your exhaust on start up. This is especially true for cars that do not get driven
regularly or have sat for a while. While this is not harmful to the engine
if after starting you get the engine up to operating temperature it can be quite
embarrassing. There is nothing worse than having all eyes on you as you step
into your 911 only to have a gigantic smoke screen come from the exhaust on
start up.
The majority of this smoke on startup comes from oil from the oil tank migrating
back into the motor. Rothsport has come up with an ingenuous solution to this
problem by designing an oil inlet check valve that restricts the flow of oil
back into the motor and opens instantly on start up. Installation is quick and
easy and a perfect solution for cars that sit for long periods of time. Note;
the valve is clearly marked with an engine side and a tank side. Failure to
install the check valve in the right orientation will lead to oil starvation and
catastrophic damage to your engine. Please make sure to read all the instructions
and double check the orientation of the valve when installing."
What do you think?

There is already a spring check valve in the system.

Well, I wonder about that.
Having lived with P&W radials for about 50 years and comparing the
incidence of hydraulic lock between P&W and the Ivchenko series engines
I would guess the ratio is somewhere around 1/100.
A major design difference lies in the location of the static oil flow
check valve. In P&W engines this valve is NOT integral to the oil
pump. It is a relatively large, lightly spring loaded, poppet style
valve positioned immediately downstream of the oil pressure outlet. It
is readily removable for inspection.
With this installation it does not matter how the leakage oil gets
through the static pump (and it does!) it is stopped at that point. Of
course if that valve develops a leak hydraulic lock can be the result
and it has happened but is a pretty rare occurrence. Not the case with
the M14 etc. it is almost to be expected at some time in the life of
the engine.
For what it=99s worth I would suggest that the valve in the
Ivchenko series is incapable of preventing leakage flow through the pump
in the static condition and I think history has proved me correct.
Cheers;
Walt
