Abstract: A solenoid assembly (23) includes a coil assembly (65) having at least one coil winding (73) and an electronic circuit assembly (67), which is in electrical communication with the coil assembly (65). The electronic circuit assembly (67) has a printed circuit board (79) and at least one electronic component (81), which is surface mounted on the printed circuit board (79). A coating material (85) coats all of the plurality of external surfaces of the surface-mounted electronic component (81). A casing (87) over-molds an outer longitudinal surface (77) of the coil assembly (65) and all of a plurality of external surfaces of the electronic circuit assembly (67).

Abstract: An integrated valve system (51) for use with a variable displacement hydrostatic pump (11), including a relief and check valve assembly (75) and a pressure override (POR) section, operable to communicate pressure above a predetermined POR setting from the high pressure side (15) of the HST closed loop to a stroking cylinder (29) to destroke the pump (11). A high pressure relief spring (83) determines the relief setting, and a POR compression spring (109) determines the POR setting, the relief spring and the POR spring being seated independently of each other, such that the POR setting may be adjusted without effecting the operation of the relief and check valve assembly (75).
