Abstract
Abstract A pneumatic governor for a fuel injection pump of an internal combustion engine comprises a housing containing five chambers in a row with a plurality of diaphragms separating the chambers from each other. An output member of the governor is drivingly connected to the first diaphragm, the first chamber being disposed on the same side of said housing as the output member. The first and third chambers communicate with the ambient atmosphere and the second chamber communicates with the fifth chamber. A rigid central portion mechanically connects all the diaphragms except the first, and a nozzle member is connected with the rigid central portion to establish communication between the fourth and fifth chambers. A spring-biased valve is in the fifth chamber for controlling communication between the fifth chamber and ambient atmosphere, the nozzle being controlled by the operation of the valve. The fourth chamber communicates with the intake manifold of the engine. A plurality of springs of different stiffness selected in accordance with a desired mode of operation of the engine connect the rigid central portion with the first diaphragm in an arrangement such that the springs are operated in succession.

Claim 1
Independent Claim
204 words
A pneumatic governor for a fuel injection pump of an internal combustion engine, comprising: a housing, five chambers disposed within said housing in a row; a plurality of diaphragms separating said chambers from each other; an output member of said governor drivingly connected to the first one of said diaphragms; the first said chamber being disposed on the same side of said housing as said output member, said first chamber and said third chamber communicating with ambient atmosphere, said second chamber communicating with said fifth chamber; a rigid central portion mechanically connecting all said diaphragms save said first one; a nozzle member connected with said rigid central portion, said nozzle being adapted to establish communication between said fourth and said fifth chambers; a spring-biased valve in said fifth chamber, said valve controlling communication between said fifth chamber and ambient atmosphere, said nozzle being adapted to control the operation of said valve; said fourth chamber communicating also with the intake manifold of said engine; a plurality of springs of different stiffness selected in accordance with a desired mode of operation of said engine; said springs connecting said rigid central portion with said first diaphragm, the arrangement being such that said springs are operated in succession.
Claim 2
Dependent Claim

A pneumatic governor for a fuel injection pump of an internal combustion engine, comprising: a housing, five chambers disposed within said housing in a row; a plurality of diaphragms separating said chambers from each other; an output member of said governor drivingly connected to the first one of said diaphragms; the first said chamber being disposed on the same side of said housing as said output member, said first chamber and said third chamber communicating with ambient atmosphere, said second chamber communicating with said fifth chamber; a rigid central portion mechanically connecting all said diaphragms save said first one; a nozzle member connected with said rigid central portion, said nozzle being adapted to establish communication between said fourth and said fifth chambers; a spring-biased valve in said fifth chamber, said valve controlling communication between said fifth chamber and ambient atmosphere, said nozzle being adapted to control the operation of said valve; said fourth chamber communicating also with the intake manifold of said engine; a plurality of springs of different stiffness selected in accordance with a desired mode of operation of said engine; said springs connecting said rigid central portion with said first diaphragm, the arrangement being such that said springs are operated in succession.
Claim 3
Dependent Claim
127 words
A governor, according to claim 1, wherein said fourth chamber communicates with said intake manifold of said engine through the flow chamber of a diaphragm mechanism, said mechanism having a spring-biased diaphragm separating said flow chamber from a closed chamber of said mechanism, said spring-biased diaphragm having a throttling orifice provided therethrough; said communication between said fourth chamber of said governor and said intake manifold also including a nozzle cooperating with a valve, said last-mentioned valve being adapted to be controlled by a pivoted lever connecting said mechanism with a fuel supply control rack of said fuel injection pump; said last-mentioned valve being movable mounted in an additional chamber directly communicating with said last-mentioned nozzle, said last-mentioned valve controlling communication between said additional chambEr and ambient atmosphere.
