Pumpenvalves? Does that mean piston valves?

It's an early valve design. A double piston, with each piston having only two passages - one straight through and the other with one port on the the side and the other at the bottom.

These days, you will likely see Pumpenvalven only in the horn section of orchestras in Vienna.

If you're lucky enough to attend a Vienna Philharmonic concert, these horns are unmistakable!

I always thought these were Vienna Valves. Pumpen were sorta squat piston valves. The ones we associate with pistons today are Perinet valves.

Those are Berlin (or Berliner) valves.

I've seen the term "pumpen" applied to both Vienna and Berlin valves, though more often to the Berlin style.
