The invention relates to a tyre valve for a pneumatic tyre of a vehicle, having a valve stem extending from the air inlet end to the air outlet end and having an outside thread on its outside circumference and a collar at its air outlet end for a rim well carrying the pneumatic tyre and a fastening thread for an air pressure sensor or other device to be fastened to the valve stem and positioned inside the pneumatic tyre, exhibiting a union nut with an inside thread for screwing onto the outside thread in order to clamp the rim base between the union nut and the collar, with the valve stem being inserted through a rim bore, with a plastic valve cap, with a deformable element located on the outside circumference of the valve stem and/or an inside circumference of the union nut. The tyre valve according to the invention is characterised in that the union nut and, if the deformation element is located on the inside circumference of the union nut, also the deformation element, exhibit a minimum inside diameter that exceeds the maximum outside diameter of the valve cap.

Tire valve for a pneumatic tire of a vehicle

Air pressure measuring device () for a vehicle wheel (), having a valve body () which constitutes a first element () and which can be inserted in a through-hole () in a vehicle wheel rim (), having a cap nut () which constitutes a second element () for axially tensioning valve body () on the vehicle wheel rim (), wherein when the air pressure measuring device () is in the installed state a threaded connection () is created between the valve body () and the cap nut (), consisting of a thread () formed on the valve body () and a thread () formed on cap nut (), wherein, in order to create one of the two threads () both elements () are made from materials of different hardnesses, a self-cutting thread () is produced in the element () that is made of the harder material, and a deforming section () is produced in the element () that is made of the softer material, in and in which the other thread () can be created by cooperation with the self-cutting thread ().

Air pressure measuring device for a vehicle tire and method for assembling the air pressure measuring device

A tire valve having a valve body engaging in a rim bore of a rim, in particular vehicle rim, which valve body forms a lower valve body section arranged on a side of the rim, in particular in the rim interior, in the assembled state, and an upper valve body section projecting from the rim bore, and in the region of the upper valve body section is designed to cooperate with a union nut, wherein the lower valve body section forms a ring shoulder offering an abutment for a flat edge section of the rim bore, and in which a ring groove which is open to the edge section is molded, and against which the edge section can be gripped by tightening the union nut, and a molded seal made from resilient material is provided to seal the rim bore with respect to the valve body, so that in the assembled and gripped state, an annular chamber section of the molded seal engages in the ring groove and rests in sealing manner on the edge section of the rim bore.

Tire valve and molding seal for a tire valve

A residual pressure valve () for a flow medium, in particular for air, the flow passage () of which is arranged in a valve housing () and is designed so as to allow flows to pass in different directions and so as to be interrupted by an at least partially movable sealing element () depending on the pressure of the flow medium, wherein an energy store () which is in particular designed as a pressure spring, the sealing element () is seated against a counter element () in a sealing manner when the flow medium drops below a minimum pressure in order to interrupt the flow passage (), and wherein the flow path () has two separate bores () which are arranged coaxially in relation to one another and are connected to one another by at least one connecting channel ().

Residual pressure valve

A valve device having a valve body () releasably connected by a retaining unit () to a housing () designed for receiving electronic tire pressure measuring device, so that the retaining unit fixes the valve body in a relative position to the housing in a locked state, and the valve body can be displaced in an axial extension direction relative to the housing and released from the same in an unlocked state. The retaining unit is provided on or in the housing, so that it engages laterally in a jacket-side locking segment of the valve body for producing the locked state, and are designed so that the retaining unit is secured or locked on or in the housing in the locked state.

Valve arrangement

A valve arrangement () comprising a valve body () for inflating and deflating a vehicle tire and comprising a measuring device () for measuring the tire pressure, in which the measuring device () is secured on the valve body () against axial movement in a pulling direction (Z) away from the valve body () by a securing element. The securing element has a profiled element () with a fixing element () acting on the valve body (). Furthermore, a construction kit for such a valve arrangement is provided. The profiled element can connect the valve body () in a signal-conducting manner to an electronic transmitting unit.

Valve arrangement and construction kit for a valve arrangement

The invention is based on a valve with a valve body () having: an air duct () which penetrates the valve body (), in particular in the axial direction (), and a valve foot () which is formed, in particular in one piece, with the valve body (), on an end () of the valve body () which is proximal with respect to a rim edge in the installed position, wherein a distal end () of the valve body () is provided to engage through a valve hole in the rim edge, and the valve foot () is provided for arrangement on a tyre-side side of the rim edge. In order to permit easier removal of the valve (), in particular even on a side of the rim edge facing away from a tyre, the invention provides for the valve foot () to be provided to engage through the valve hole, and for a securing element () which is separate from the valve body () and which projects over the valve foot (), in particular in the radial direction, to be arranged at the proximal end (), said securing element () being provided for arrangement on a tyre-side side of the rim edge.

Valve, tire, rim and wheel

The invention relates to a tire valve () comprising a valve body () which penetrates a bore () of a rim (), particularly a vehicle rim, embodies a bottom valve body section () that is disposed on one side () of the rim (), particularly in the interior of the rim, in the mounted state as well as a top valve body section () that protrudes from the rim bore (), and is configured so as to cooperate with a cap nut () in the area of the top valve body section (). The bottom valve body section () forms a stop collar () which is used as an abutment for a flat peripheral section () of the rim bore () and widens the bottom valve body section () relative to the top valve body section () beyond an internal width of the rim bore (21). The peripheral section () of the rim bore () can be braced against said stop collar () by tightening the cap nut ().
