Re: My column-style steamengine - the Valves

Hello,
for the feedwaterpump were made two "mushroom"-valves. At speed higher than 600 rpm the ballvalves destroy the ball seats in the pump body - experience from the operation of my steam lorry MARTIN. The valves are "pressed" with very light springs to its seats so they work ut to 1.500 rpm - experience from MARTIN.

The valve chest is placed at the upper end of pump chamber to allow the air to leave the system.
The valves in the condensate pump are rubber plate types (NBR). They are small enaugh and noisy in service.

Dietrich,
Good job on the check valves, I like the disc type check valves also. Ball checks are not as reliable.

Hello,
when i get the engine there was mounted a wick oiler with a cup from a solid aluminium block and plugged pipes so the oil could leak out.

At my model steam lorry was a similar problem and the solution was to built a new soldered cup and screwed connections.

The wicks with its handles from drilled copper wire.

It is easy to remove the wicks from working position and to protect the fingers from getting oily.

The displacement lubricator

Hello,
the displacement lubricator was made from bar stock and a short pipe. The regulating valve is outside of the body so it can be filled with more comfort.
The valve stem has a 20 degree tip and is tightened with an O-Ring.
