Abstract (en)
A cylinder block assembly 400 of a hydraulic unit includes a cylinder block 402 having a plurality of piston bores 404 arranged circumferentially about a central axis A of the cylinder block assembly 400 and extending through a first face 406 of the cylinder block. Each of the piston bores 404 has a pitch diameter defined radially with respect to the central axis A of the cylinder block assembly 400. A second face 412 of the cylinder block 402 has pressure ports 420 that extend from the piston bores 404. The cylinder block assembly 400 further includes a balance plate 414 coupled to the second face 412 of the cylinder block. The balance plate 414 includes apertures 418 that align with the pressure ports 420, where a cylinder block assembly outer length is defined between the first face 406 of the cylinder block and an outer face of the balance plate. A ratio of the pitch diameter to the cylinder block assembly outer length is between 1.24 and 1.27.
