Abstract (en)
[origin: CA3144505A1] The hydraulic cam injection system (100) comprises an injection valve (50) housed in a tubular injection nozzle (54), a gap being left between a valve stem (51) of the valve (50) and the inner surface of the tubular injection nozzle (54) to allow an injectable fluid (58) to flow from pressurising means (10) while a receiving piston (62) rigidly connected to the valve (50) receives, on the one hand, the pressure of the injectable fluid (58) to keep the valve (50) closed, and on the other hand, the pressure of a hydraulic fluid (60) to open the valve (50), an injection cam (67) being capable of moving the receiving piston (62) by means of a transmitting piston (69) and the hydraulic fluid (60).
