Zusammenfassung:An additive manufactured (AM) hydraulic control assembly includes a first AM hydraulic passage having a first tubular wall defining a first fluid passage, a second AM hydraulic passage integrally formed with the first AM hydraulic passage and having a second tubular wall defining a second fluid passage, and an AM wall integrally formed with the first and second AM hydraulic passages and fluidly separating the first and second fluid passages. At least one of (i) a hydraulic control orifice is formed in the AM wall and configured to regulate fluid flow and pressure between the first and second fluid passages, and (ii) a ball seat is formed in the AM wall and a check ball is disposed in one of the first and second fluid passages and configured to selectively seal against the ball seat to facilitate preventing fluid flow therethrough.
