摘要： A retention mechanism for releasably securing a receptacle to another component includes a ratchet lever pivotally mounted about a screw, a torsion spring having a first end attached to a first end of the lever and being biased to pivot the lever about the screw axis to a first, locked position. A second end of the lever engages, in use, with teeth provided on the receptacle to secure the receptacle against rotation relative to the other component. The mechanism has a compression spring arranged to bias the lever in an axial position such that, in the first, locked position, the second end of the lever engages the teeth. The first end of the lever is configured to receive pressure from a user against the force of the torsion spring to pivot the lever about the axis such that the second end of the lever disengages from the teeth.

摘要： 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.

摘要： 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.

摘要： A filtration assembly includes a filter housing and a filter element. The filter housing includes a base and a cover including an underside having one or more retainer features. The cover is removably coupled to the base. The filter element is removably installed within the base when the cover is coupled to the base. The filter element includes filter media and an endplate coupled to one end of the filter media. The endplate includes an outer perimeter and one or more engagement features protruding from the outer perimeter. The one or more engagement features engage the one or more retainer features in the cover upon installation of the endplate into the cover, thereby coupling the endplate to the cover.

摘要： A filter element of at least one of a vehicle and an internal combustion engine may include an annular filter body, an inner frame supporting the filter body, an upper end plate and a lower end plate arranged axially on the filter body, a pin eccentrically arranged on the lower end plate, a plurality of centring elements, and a positioning web. The annular filter body may surround a cylindrical inner space. The plurality of centring elements may be arranged distributed in a circumferential direction of the filter body around the first plate opening, protrude axially into the inner space, and respectively have a chamfer. The positioning web may be arranged on at least one of the upper end plate and the inner frame in the circumferential direction between two centring elements of the plurality of centring elements and extend parallel to the two centring elements.

摘要： A filter assembly includes a housing, a proximal end cap, and a nut plate. The housing defines a longitudinal axis and includes an inner surface surrounding the longitudinal axis. The proximal end cap is disposed within the housing and defines a central aperture. The nut plate is disposed within the housing and includes a flange portion and an outer wall. The flange portion is disposed within the central aperture. The outer wall includes a plurality of protrusions disposed about the longitudinal axis. At least one of the plurality of protrusions engages the inner surface to prevent rotation of the nut plate relative to the housing.
