Abstract:
1. In a radial piston pump for high-pressure fuel delivery in fuel injection systems of internal combustion engine, including a number of pump elements ( 9 ) arranged radially in relation to a drive shaft ( 3 ) supported in a pump housing ( 1 ), the pump elements ( 9 ) being actuated by the drive shaft ( 3 ) and each having a respective inlet side ( 19 ) and high-pressure side ( 21 ), and with high-pressure conduits ( 27 ) in the pump housing ( 1 ), each of which connects the high-pressure side ( 21 ) of at least one pump element ( 9 ) to a high-pressure connection ( 33 ) in the pump housing ( 1 ), the improvement comprising a first one of the high-pressure conduits ( 27 ) which connects directly to two pump elements, and a second of the high-pressure conduits which connects directly to connecting another pump element and also connects directly to said first high-pressure conduit at a junction which has an angle (α, β) which is substantially 90°, and wherein the high-pressure connection ( 33 ) connects directly to only one of said first or second high-pressure conduits, and does so at an angle (α, β) which is also substantially 90°.
