Abstract

A retraction device for a valve seat, see Division F2, comprises a fork-shaped lever 34 having studs 35 to bear against the edges of the seat, and or hook-shaped catch 37 intended to engage a recess 38 in the valve body. In Fig. 7, not shown, the seat is retracted by a plain fork-shaped lever (48).
