| 2 119,063 The usual throttle D is situated at the outlet of the apparatus leading to the engine. The air inlet control valve A which is shewn in its closed position in Fig. 1 is mounted on a spindle a, one end of which passes through a boring in the wall of the inlet piece and has secured to it one end of a lever A¹. Connected to the free end of the lever A¹ is an adjustable rod or link E the other end of which is coupled to one arm D² of a bell crank lever D¹ which operates the throttle D.{John DeLooze - Company Secretary} In order that the amount of opening given to the valve A may be varied relatively to the throttle D or may be proportionate to or equal to that of the throttle, the connection between the rod E and arm D² is an adjustable one. A convenient method of effecting such adjustment is by providing a series of openings in the arm D² through any one of which a pin e on the rod E may be passed to vary the effective length of the arm D². Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is:— 1. In a carburettor such as described furnished with an expansion chamber which expands towards the induction pipe from the inlet for fuel mixture and into which the air and liquid fuel are introduced by a single opening the combination with the air inlet of a valve operatively connected with the throttle for the purpose described. 2. In a carburettor such as described furnished with an expansion chamber, which expands towards the induction pipe from the inlet for fuel mixture and into which air and fuel are introduced by a single opening the combination with a valve in the air inlet of mechanism connecting the air control valve with mechanism for operating the throttle and mechanism for adjusting the connection between the two valves for the purpose described. 3. In a carburettor such as described the complete mechanism for effecting the operation of the throttle and air-inlet valves substantially as described or illustrated in the accompanying drawings.
