Abstract (en)
The pump has three cylinders (17) set in the housing (23) 120 degrees apart. Each piston has a hemispherical inner end (59) engaging a shoe which engages on a triangular ring (31) on an eccentric shaft. Two galleries (51a,51b) connect the working ends of two cylinders. The first has a side branch leading to a magnetic control valve (15) which releases fuel back to the inlet via a reservoir. The second is connected to a relief valve (55).
