A fluid cylinder block, comprising:
- a body having a plurality of bores formed therein that intersect at a junction, each of the bores having a first diameter in the body and a portion extending into the junction having a second diameter;
- and
- a stress distributing joint comprising a first groove formed in the body adjacent to a first bore of the plurality of bores and a second groove formed in the body adjacent to a second bore of the plurality of bores, wherein the grooves include a major dimension that is greater than the first diameter and the second diameter of the first and second bores.
A fluid end, comprising:
- a body having a plurality of bores formed therein that intersect at a junction, each of the plurality of bores having a first diameter and a portion extending into the junction having a second diameter;
- a stress distributing joint comprising a groove formed in the body in a first bore of the plurality of bores, wherein the groove includes a major dimension that is greater than the first diameter and the second diameter the first bore;
- and
- a plunger disposed in one of the plurality of bores.
