Such devices. as shown iii the prineipal ligures of the drawings. are minstrncted as t'ollows: Such devices. as elearlv seen in Fig. 4. einhraee an auxiliary c vliniiler $30 Closed at one end and provided at its closed end with a passage 37 connnunii-ating with the interior of the cylinder. a piston 3tlin said c viinder a piston rod 39 attaehed to said piston. a lever 4() which is mounted upon a pivot orV fiileruni 41 secured to the valve easing. and a lever Llid eonneeted at one end to the valve casing and `at its opposite end tothe lever 40, said lever 42 heing arranged to extend over the upper or outer face of the. liloek 35 and having hearing engagement with said block. These parts are so arranged that the fluid. under pressure within the cylinder, entering the auxiliarv c vlinder i through the. openingl 21T. acts on the piston 3S. and the pressure.

The diaineter of the open` ing 13h is inade larger than the diameter ot the evlinder fit1 so that when the dish 43 is detached the piston 23S may he removed or inserted through said opening.
