The present invention relates to an electromagnetic device (10) comprising: —an electromagnetic system (60), —a fuel vapour outlet conduit (30) extending the electromagnetic system (60), —a first housing (61), in which the electromagnetic system (60) is arranged. The invention is characterized in that the fuel vapour outlet conduit (30) is arranged in an intermediate housing (71).

A fuel filter device includes a bag-shaped filter member filtering fuel that is drawn into a fuel pump, an inner frame member retaining the filter member in an expanded state, and a mounting member connected to the inner frame member and serving to communicate an internal space of the filter member with an outside. A valve chamber is defined by the inner frame member and the mounting member, and a check valve serving to prevent backflow of fuel is disposed in the valve chamber. The check valve includes a flat-plate shaped valve body having elasticity. The check valve opens against its weight when the fuel pump is operated, and the check valve closes due to its weight when the operation of the fuel pump is stopped.

In at least some implementations, a jet pump includes a main body having a first inlet, an inlet passage communicated with the inlet, a second inlet, an intake passage communicated with the second inlet, an outlet, and an outlet passage communicated with the outlet and with the intake passage, a jet carried by the main body and having a jet inlet communicated with the inlet passage so that fluid flowing in the inlet passage flows through the jet inlet, and a jet outlet having a flow area less than the jet inlet and less than the inlet passage. The main body is formed in one piece and the jet is a separate piece of material that is inserted into the inlet passage after the main body has been formed.

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.

A fuel filter element has a screen fabric as a filter medium and a support tube supporting the screen fabric. A valve body guide for guiding a spherical valve body is provided. The valve body guide has a fluid channel and one or more support ribs for supporting the spherical valve body. The support ribs extend along a longitudinal direction of the fluid channel and project radially into the fluid channel. A filter assembly with such a fuel filter element is provided. The filter assembly has a ball valve with spherical valve body and a filter housing with a valve seat for the spherical valve body of the ball valve.

A valve unit has a plate-shaped valve body with a closure section and a connection section. The valve body has a cutout surrounded by a frame. The closure section has a closure tab that, beginning at a first fastening section at the frame, projects into the cutout. The connection section, beginning at a second fastening section at the frame, projects into the cutout and has a contact tab and a fastening point. The first and second fastening sections are arranged opposite each other at the frame along a longitudinal axis of the valve body. A filter head for the valve unit has a valve seat for a seal body of the closure section of the valve body. A fastening pin of the filter head fastens the connection section of the valve unit. A contact region of the filter head contacts a positioning region of the valve unit.

A filter assembly that comprises a housing, an outer filter element, and an inner filter element. The outer filter element is positionable within the housing and comprises an outer filter media. The inner filter element is positionable within the outer filter element and comprises an inner filter media, a media support structure, an inner top endplate, and an inner bottom endplate. The inner top endplate comprising a top rib that extends continuously around a portion of a top surface of the inner top endplate.
