Abstract: A water drainage device for a filter module is provided with a valve housing that has a valve bore, a valve body received at least in sections in the valve bore, an actuation rod for actuating the valve body, and a coupling device operatively connecting the actuation rod with the valve body and enabling a tilting of the actuation rod in relation to the valve body. The water drainage device can be transferred from a closed state, in which the valve body seals in relation to the valve seat of the valve bore, into an open state, in which the valve body is lifted off the valve seat, and in reverse. The filter module has a filter housing with a housing top part. The valve body, upon transfer of the water drainage device from closed state into open state, moves toward the housing top part of the filter housing.

Abstract: A filter module for filtering fuel in an engine system includes a primary filter, a secondary filter, and a module housing. A drain valve is movable between a closed position blocking a drain port in the module housing, and an open position. A service valve assembly is positioned at least partially within a cross passage in the module housing and adjustable from a closed configuration blocking a primary-side fuel passage from a secondary-side fuel passage in the module housing, to an open configuration, to drain fluids from the filter module by way of the single drain port.

Abstract: A liquid filter insert for a liquid filter has a prefilter element and a main filter element connected to the prefilter element. Prefilter element and main filter element are arranged on top of each other in an axial direction relative to a longitudinal axis of the liquid filter insert. A connection provides a flow path for liquid to flow from the prefilter element to the main filter element. The prefilter element is provided with a water separation unit and is further provided with a filter medium. The water separation unit is arranged between the filter medium of the prefilter element and the connection such that the liquid, after passing through the filter medium, flows through the water separation unit into the connection. The water separation unit has a water discharge channel for water separated from the liquid that extends axially at least partially through the main filter element.

Abstract: A fuel filter assembly utilities a filter with a filter head having a primer. The primer includes a diaphragm and a valve plate which define a primer reservoir. A first check valve and a second check valve are mounted to an opening and a plurality of orifices. The first check valve consists of a ball valve. The use of a ball valve allows for an increased flow rate through the opening.

Abstract: A fuel pump motor system 10 for providing fuel to an engine includes a pump motor assembly 12 having a rotor 16 for generating a rotor magnetic field; a shaft 21 mounted with respect to the rotor such that rotation of the rotor rotates the shaft, an impeller 20 mounted to the shaft, and a stator 18 for generating a stator magnetic field. The stator is associated with the rotor such that interaction of the rotor magnetic field and the stator magnetic field causes the rotor and thus the shaft and impeller to rotate thereby moving fuel from an inlet 24 to an outlet 26 of the pump motor assembly. A filter structure 14 is integral with the pump motor assembly and shares a substantially sealed, non-porous barrier 25 therewith. The filter structure includes filtration media 28 constructed and arranged to filter fuel received from the outlet of the pump motor assembly prior to delivery to an engine.
