A diffuser for a return line on a hydraulic tank may include a coupling portion configured for coupling in fluid communication with a return port of the hydraulic tank and for receiving return fluid along an incoming longitudinal direction. The diffuser may also include a dispersion portion in fluid communication with the coupling portion and configured for dispersing the return fluid radially. The diffuser may also include a manifold arranged around the dispersion portion and configured to direct the return fluid circumferentially and axially.

A ball float vent valve includes a valve body having an inlet port, an outlet port and an axial passageway there-between. The passageway may be defined by a cylindrical inlet chamber, a cylindrical outlet chamber and a tapered seat connecting the inlet chamber and outlet chamber. The outlet chamber may include an annular retaining groove proximate the outlet port. A spherical float may be positioned in the outlet chamber. The float may be dimensioned to seal the passageway when seated on the tapered seat. A retainer positioned in the retaining groove may include an outer crescent region having a plurality of apertures, a center region dimensioned to retain the float in the outlet chamber, and a linking region connecting the outer region to the center region.

A splashguard is disclosed for use with a tank. The splashguard may include a main channel formed by an elongated base plate and side walls extending generally orthogonally from the elongated base plate by a first distance. The splashguard may also include a first end channel formed by a base plate and side walls extending generally orthogonally from the base plate by a second distance greater than the first distance. The first end channel may also be formed by an end wall extending generally orthogonally from the base plate by the second distance. The splashguard may further include a second end channel substantially identical to the first end channel. A first flow path may be maintained between the elongated base plate of the main channel and the base plate of the first end channel. A second flow path may be maintained between the elongated base plate of the main channel and the base plate of the second end channel.
