'7 The invention relates to valves of the. general
type having a rock shaft, an'arm secured to said
rock shaft, and a valve secured to said armfor
cooperation with a- valve seat, and while it is’
5 intended primarily for actuation by a gasometer
to control the feeding of natural or_manufactured gas to a gas engine, it is usable also for
various other purposes.

projecting bearing necks t5 and I6 having axially
alined bearing openings I1, the axes of which
are parallel with the ?at face J3. A rock shaft
I8 is mounted in the bearing openings ll‘ and
projects beyond the neck it for connection with 5
suitable operating means, a portion of which is
shown at H). .The outer end of the neck I5 is
provided with a threaded cap 20 to be ?lled with.
