Port and Helix pumps are cam driven plunger type pumps that run at one-half engine rpm for four stoke engines and at the same rpm in the case of a two stroke. The pump is similar to that of a radial piston type pump but instead of a piston it has a machined plunger that has no seals. When the plunger is at top dead center, the injection to the cylinder is finished and it is returned on its downward stroke by a compression spring.Because the height of the cam lobe cannot be easily changed, the amount of fuel being pumped to the injector is controlled by a rack and pinion device that rotates the plunger allowing variable amounts of fuel to the area above the plunger. Inlet and outlet ports are located on two sides of the pumps cylinder walls allowing fuel to flow through the compression chamber until the plunger is driven up closing the two ports and starting the compression motion. The outlet port feeds back into the fuel tank/settler of the engine. The fuel is then forced through a stop check valve, to prevent backflow to the injector nozzle at pressures that can exceed 18,000 psi.
