Abstract
An engine speed and loss of oil pressure control arrangement for an engine such as is used in transport refrigeration and is operative at a low speed and a high speed, the arrangement including two axially aligned pistons 12 and 36 into adjacent cylinders 10 and 34, respectively, the first piston 12 moving from an engine off position to a low speed position upon closure of the valve 22 when engine operation is initiated, this forcing the second piston 36 to a low speed position which effects said low speed through leakage 40 to the engine speed control means, the second piston 36 moving further to the right to an engine high speed position upon opening of valve 28 in a conduit leading from the first cylinder to the second cylinder.
