Abstract (en)
[origin: WO2013091218A1] A pump (10) includes a drive assembly (14) having a drive shaft rotatable about a drive axis (98), and an eccentric (106) coupled to the drive shaft for rotation therewith. The eccentric (106) includes a shaft portion (118) defining an eccentric axis (122) that is offset from the drive axis (98). The shaft portion (118) includes a shaft end defining a first alignment feature (124). A piston (166) is rotatably coupled to the shaft portion (118) and defines a second alignment feature (190). A cylinder (30) reciprocatingly receives the piston (166). Positioning the first alignment feature (124) in a predetermined orientation with respect to the second alignment feature (190) locates the piston in one of a top-dead-center position and a bottom-dead-center position with respect to the cylinder (30). A method for orienting a first piston (166) and a second piston (166) in a dual piston pump (10) is also provided.
