摘要： A fuel injector assembly for an emissions-based EMD 710 locomotive diesel engine. The fuel injector assembly includes a needle slidably positioned within a bore of a valve body of the injector assembly, where fuel pressure introduced into a bore chamber causes the needle to open a spray tip. A spring mounted within the bore forces the needle to close the spray tip when the fuel is not being applied. The spring is a dead coil spring including inactive coils where at least portions of the coils at both ends of the spring are in intimate contact with each other so as to reduce spring wear during operation of the assembly. Because the dead coil spring has reduced wear, the VOP set point of the fuel injector assembly can be reduced, which reduces NOx emissions.

摘要： The invention relates to a radial piston pump comprising a drive shaft mounted in a pump housing and preferably comprising a plurality of pistons (1) which are arranged in a respective cylinder chamber (2) and in a radial manner with regard to the drive shaft. A plate (3) is mounted on the piston ends facing the drive shaft. The plate comprises a pocket hole (9) in the middle, in which the end (9) of the accompanying piston (1) is accommodated. The piston (1) has a groove (7) on the circumference thereof, in which a retaining ring (6) is placed in order to fasten a plate holder (4) on the piston (1), said plate holder holding the plate (3) on the piston (1). The inventive pump is characterized in that a cylinder depression (26) is placed in the plate at the edge of the pocket hole (9), whereby the diameter of the cylinder depression (26) is dimensioned in such a way that the clearance between the retaining ring (6) and the circumference of the cylinder depression (26) is smaller than the depth of the groove (7).
