A housing module of a fluid treatment module of a fluid system is provided with a fluid housing with inlet and outlet for fluid. The fluid housing has a housing part with a receiving chamber for a fluid treatment component for treatment of fluid and an installation opening, closable by a housing closure part, for installation of the fluid treatment component in the receiving chamber. A housing connecting section is provided for connecting the housing part and the housing closure part to each other. The housing module has an externally positioned support structure that surrounds the housing part like a sleeve and has a reinforcement region that extends about the housing connecting section. The support structure has a fastening region for attachment of the housing module on a holding component of the fluid system. The connection of the housing part with the housing closure part is a direct connection.

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a top annular mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and a connecting portion that extends at least radially outwardly from the top annular mounting portion to the sealing portion.

A carburetor includes a body and a fuel bowl coupled to the body. A fuel bowl chamber is defined by the body and the fuel bowl. A fuel supply passageway fluidly couples a fuel supply inlet of the carburetor with the fuel bowl chamber. A fuel metering unit is coupled to the body of the carburetor. A first filter is disposed in one of the fuel supply passageway and the fuel bowl chamber, and a second filter is disposed in the fuel metering unit.

A lubricant filter housing comprises a top plate defining a first opening. A base plate is positioned opposite the top plate. The lubricant filter housing further comprises at least one sidewall which cooperatively with the top plate and the base plate defines an internal volume. A plurality of plates are axially positioned in the internal volume between the top plate and the base plate. Each plate defines a plate opening axially aligned with the first opening which cooperatively with the first opening and a portion of the base plate, defines an internal cavity for housing a filter element. The plates define a first set of fluid channels structured to deliver a lubricant to the internal cavity, and a second set of fluid channels structured to provide a coolant around the first set of fluid channels.

The present invention relates to a filter medium being at least formed of a pre-filter substrate laminated with a fine-filter substrate by means of a third binder, wherein the pre-filter substrate comprises synthetic fibers and a first binder, the pre-filter substrate working as a combined surface and depth filter, and the fine-filter substrate comprises at least a second binder and one of synthetic fibers and inorganic fibers.

A filter device includes a functional element and a filter element arranged in a filter housing. The filter element includes an enclosure positioned about a central axis and below filter material of the filter element. The enclosure includes an enclosure wall that defines an inner volume that is in fluid communication with an orifice of the functional element when the filter element is positioned over the functional element.

A liquid filter in the form of a filter element or a filter cartridge provides torsion locking relative to a filter head when the housing of such filter is threaded onto a filter head. Many embodiments employ a filter that includes a nipple portion at a top end with the torsion lock detent provided outboard of the nipple portion or integrated into the nipple portion. Many embodiments employ a simplified shoulder transition region at the top end of a torsion locked filter element. Valve actuation and/or filter differentiation is used in some embodiments. Different torsion locking arrangements, deformable thread profiles and other liquid filter features are disclosed.

A filter device for treating fluids, in particular for filtering fluids such as fuel, oil, or water, has a housing (56) with a housing pot (58), a housing cover (60), at least one inlet (88) for the fluid to be treated, and at least one outlet (82) for the treated fluid. A connecting head (12) has at least one feed (16) for the fluid to be treated and connectable to the at least one inlet (88), and/or at least one discharge (18). The connecting head (12) and the treatment element (14) can be connected to each other by means of a releasable bayonet-type connecting device (34) through the execution of a rotational/plug-in movement about a connecting axis (20) of the treatment device (10).

A system includes an oil catch compartment, at least one magnetic stud or rod, a motor compartment, and a switch. The oil catch compartment includes a first end configured for coupling to an oil filter. The at least one magnetic stud or rod is positioned along a sidewall of the oil catch compartment. The motor compartment includes a gearbox shaft and a puncturing device. The gearbox shaft is telescopically coupled to a second end of the oil catch compartment. The puncturing device is coupled to the gearbox shaft and positioned at least partially within the housing of the motor compartment or the oil catch compartment. The switch is formed on an outside surface of a battery compartment and communicatively connected to a motor coupled to the gearbox shaft. The switch is actuatable to cause the motor to advance the puncturing device via the gearbox shaft.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.
