-1 vr.In-ordersto facilitate the startingl of said units in operation yafter they have been used v conveniently provided with a conduit 25 through which the .compressed .air which otherwise would resist the starting movement of thel pump maybe vented under lcontrol of the ,respective valves/26 eachfo'f which is mountedfto reciprocate `in respective ,cas-V ings 27, as indicatedin"FiglILV As`indicated in'Fig. III,`each valve 26 'controls a port 28 leading to the outer atmosphere throughits'vent'tuhe 29 y"but is ,continually thrust by afspring 30 .to closel such port. However, each o fsaidvalves is'adapted tov be opened by; a plunger-31 which isf'moun'ted l toV reciprocate 'fin the Vvalve casing l27 'and bythe screw 4 1' with ,theV movable Contact block 42 of insulating'material, lso as ,to close the v`ienergizing circuit of ltheflocal motor 8V i Gp,

However, each lever 72 is adapted tobetilted clockwise to move its *roller 7l past the crest yof its latch camf'70;
whereupomthe latch and switch lever34 are snapped v counterclockwise vby their' spring I63 to open the circuit and thus stop the electric motor energized thereby, `it jandnwhen said lever 72isv subjected to ai predetermined pres; sure of the fluid torv herdispense'd. y l `uch'pressu're is variable byairial adjust ment of the spring 76 which is engaged at one end with thevupp'er end of said lever 72 andadjustably connected at its other endV with the casing '36, by means of the screw y77 which extends through `said casing in engagement with the nut 78 liked inl said'spring and has the lhead 79V exterior lto said casing adapted toy be turned by any suitable wrench.'
