Abstract: A spool for a spool valve assembly defines a spool longitudinal axis and includes a first land module defining a first land module circumferential surface, a second land module defining a second land module circumferential surface, and a first metering module. The first metering module has a first end cap and a second end cap. The first end cap is coupled to the first land module, and the second end cap is coupled to the second land module, to form the spool. The first metering module may further include at least two pillars extending from the first end cap to the second end cap, wherein the at least two pillars are entirely disposed within a virtual first metering module hollow cylinder area that surrounds a virtual first metering module central core area concentric with the spool longitudinal axis.

Abstract: A bracket assembly for an accumulator is provided. The bracket assembly includes a holding element. The holding element includes a body having a front surface and two side surfaces. The two side surfaces extend from the two ends of the front surface. The holding element also includes a corner portion disposed at each of the two ends of the front surface. The corner portion is formed by an angular relationship between the front surface and each of the two side surfaces at the respective end of the front surface. The bracket assembly also includes mold member extending from the inner side of the holding element. A thickness of the mold member at the corner portion is greater than a thickness of the mold member at the front surface of the holding element.
