A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. One functional element has an assembly ramp passing into a first support region perpendicular to the connection axis. The other functional element has a slide region adjoined by a second support region perpendicular to the connection axis. In connection end position, first and second support regions are positioned on top of each other relative to the connection axis.

A fluid treatment device has an exchangeable treatment unit and a connection head. A bayonet-type connection device connects connection head and treatment unit to each other by a plug-in/rotation movement about a connection axis of the treatment device and is provided with a housing connection part and a head connection part that operatively engage each other to form a connection of the bayonet-type connection device. Housing connection part and head connection part each have a mutually complementary functional element extending circumferentially about the connection axis and operatively connectable to each other. The bayonet-type connection device has a pretension element for realizing a mechanical pretension pressing the functional elements against each other. The pretension element is a spring element with outwardly projecting spring arms with radially outer end faces provided with a straight section that is tangential to a rim extending in circular shape around the connection axis.

Treatment device for treating fluids, more particularly liquid fluids, and treatment unit and connection head for a treatment device

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

Treatment device for treating fluids, in particular liquid fluids, and treatment element of treatment device

An exchangeable filter of a treatment device has a housing with a housing pot and a housing cover connected to the open side of the housing pot. The exchangeable filter is connectable to a connecting head of the treatment device with a bayonet-type connecting device. The connecting device has a housing connecting part on the housing interacting with a head connecting part of the connecting head for connecting the connecting device. The housing has an inlet for a fluid to be treated connectable to a supply conduit of the treatment head and an outlet for the treated fluid connectable to a discharge conduit of the treatment head. The housing pot has a rim at the open side of the housing pot. The rim radially outwardly surrounds the housing connecting part and axially projects past the housing connecting part in a direction away from the housing bottom.

Exchangeable filter of a treatment device for treatment of, in particular, liquid fluids and treatment device

A filter device includes in a filter housing a hollow cylindrical filter element having frontal end plates, a flow opening being made in one of the end plates. In order to interlockingly secure a pipe connection piece that communicates with the flow opening, a cover has a radial collar which forms an axial stop for the pipe connection piece.

Filter device, in particular liquid filter

A filter system () has at least one filter element (), a filter housing () having at least one first housing part and one second housing part, in particular a lid (), as well as a coupling device (). The coupling device () thereby has at least one first coupling part () and at least one second coupling part () that corresponds to it for removable coupling of the at least one filter element () to the second housing part (). The first coupling part () has one or a plurality of first latching means () and control surfaces (). The second coupling part () has one or a plurality of second latching means () that can be brought into operative connection with the one or a plurality of first latching means () and control surfaces (). At least the first and the second latching means () can be brought into functional connection when joined, and the control surfaces () and the second latching means () can be brought into operative connection when first and second housing parts () are released. The second latching means () each have three bevels (), at least two of which work together with the control surfaces () to release the second housing part () from the filter element () upon a relative rotation of the filter element () around the longitudinal axis (L) counter to the second housing part ().

Filter system and filter element

A filter device has a cup-shaped filter housing and a filter element disposed in the filter housing. A filter head is connectable to the filter housing and forms a cover for the filter housing. A spring element is provided that is acting on the filter element. The filter head has at least one first form-fit element. The filter housing has at least one second form-fit element for interacting with the at least one first form-fit element. The spring element is arranged such that the filter head and the filter housing for reaching a closed position, in which the at least one first form-fit element and the at least one second form-fit element engage each other, are movable relative to each other axially against the force of the spring element. The spring element clamps the filter element axially between filter head and filter housing in the closed position.

Filter housing with locking form-fit elements and spring loading a filter element in the housing

A filter device includes in a filter housing a hollow cylindrical filter element having frontal end plates. A port having a first sealing element is incorporated into a cover the filter housing, said sealing element being arranged coaxially relative to a second sealing element in a flow opening in the end plate.
