Injection timing control device for distributor-type fuel injection pumps
This patent describes an injection timing control device for combination with a fuel injection pump for an internal combustion engine, the pump being of the type having a suction space filled with fuel under pressure variable as a function of the rotational speed of the engine, a pumping and distributing plunger, and a roller holder carrying rollers circumferentially arranged and disposed in camming engagement with the plunger the injection timing control device comprising: a cylinder; a timer piston slidably received within the cylinder. The timer piston is coupled to the roller holder such that displacement thereof causes a corresponding change in the cicumferential position of the roller holder,; a first chamber defined at one end of the timer piston; a second chamber defined at one end of the timer piston; a second chamber defined at an opposite end of the timer piston.
