ABSTRACT:
A rotary distributor pump for supplying fuel to a six cylinder engine is adapted to supply fuel to a three cylinder engine by connecting its three inactive outlet ports to chambers and by arranging that no fuel is supplied to its pumping chamber prior to registration of its delivery passage with an inactive outlet port. In order to minimise the risk of cavitation of the fuel within the chambers they are vented to a low pressure source of fuel just before the delivery passage registers with an inactive outlet port.
