Abstract: A valve assembly includes a valve housing having a bore formed therein. The bore has an axis A and comprises a circumferentially extending groove formed at an end portion. An axially outer wall of the groove includes at least two circumferentially spaced radially inwardly extending retaining elements defining an axial slot therebetween. An end cap is received in the end portion of the bore and closes the end of the bore. The end cap includes a retaining portion that includes at least one radially outwardly extending retaining element which is shaped to be insertable through the axial slot into the groove and rotatable therein to a retaining position in which the radially outwardly extending retaining element aligns with one of the radially inwardly extending retaining elements to prevent axial withdrawal of the end cap from the bore.

Besides, the ribs help the frame lining be positioned on the wheel frame.

Abstract: The specification discloses a tire inflation pressure regulator facilitating precise tire inflation. The regulator includes a body, a two-position valve within the body, and a rotational lock. The body includes an air inlet, an air outlet, and an air vent. In one position, the valve directs air from the air inlet to the air outlet when the tire pressure is below a preset level; and, in a second position, the valve directs air from the air inlet to the air vent when the tire pressure exceeds the preset level to prevent overfilling. The valve moves rapidly between the two positions, and is unstable between the two positions. The valve includes a regulator enabling the preset level to be adjusted. The rotational lock enables the regulator to be screwed onto a tire stem, but prevents removal of the regulator from the tire stem without a key.

Abstract: A valve assembly for a dunnage bag wherein in the valve body a valve diaphragm is mounted on a shaft and is supported by a mounting bar such that the valve diaphragm may be reciprocally moved from the closed position to the open position by a simple axial push on the valve shaft. The valve shaft is retained in the mounting bar in an orifice and the shaft diameter is enlarged at its end distant from the valve diaphragm so as to generate a frictional force fit or lock in the open position to facilitate the removal of air from the bag. The valve may be released form the friction lock by the air pressure of a recharged bag and/or by the manual movement of the valve diaphragm and shaft axially toward the open end of the valve assembly.

Abstract: With the invention, a measuring device is proposed for the measurement of motor vehicle wheels (10) in which, with the aid of profiled measuring rolls (20), the different areas of the rim (11) can be measured. These measuring rolls (20) are arranged so they can be displaced in the X and Z directions on positioning and measuring sleds (40) designed as cross-sleds. The cross-sleds (40) are equipped with linear motors (41, 43), with which the positioning and pressing pressure of the measuring rolls can be varied and which, at the same time, detect the deviations occurring during the measurement. The measured data thus obtained are processed in a process computer.

It comprises a valve pneumatically connectable to the storage vessel to admit and release pressurized gas into and from the storage vessel; a connecting chamber for pneumatically connecting the valve to the pneumatically operable device to conduct pressurized gas released through the valve to the pneumatically operable device; and a manually operable control operable to release pressurized gas from the valve into the connecting chamber.

Abstract: A theft resistant valve cap including a liner adapted for threaded engagement with a standard pneumatic tire stem valve, a sleeve rotatably mounted with the liner to shroud it and an interlocking feature to selectively prevent axial displacement between the liner and the sleeve. The liner includes a hollow body with first and second opposed ends that features shoulders positioned proximate to one of said opposed ends. The shoulders, when employed with the sleeve rotatably mounted with the liner to shroud it, facilitates restricting removal of the cap from the valve stem to authorized individuals, only. Specifically, an interlocking mechanism extends between the liner and the sleeve and limits axial movement therebetween, while allowing rotational movement. To remove the cap from the valve stem, a key is employed which forms an interference fit with the shoulders in the liner, once exposed.

To make possible a specified flushing of the pipes closed with the sealing plugs, the piping connector exhibits a housing which can be connected to a piping connection point, with a screw-on connector on one end so that it can be screwed to the piping connection point in question, and a water shut-off mechanism on the opposite end, which is protected by means of a screw-on cover.

Abstract: A valve cap adapted to be screwed onto the valve of a pneumatic tire gives a pressure drop indication. To this end the valve cap comprises a deflectable diaphragm which separates the housing interior into a first chamber adjacent a transparent section of the closed housing end portion and a second chamber which is in communication with the tire interior through a port formed in a transverse housing wall and through the open tire valve. When the valve cap has been tightly screwed onto the tire valve and the tire valve has been opened, the desired tire pressure will be built up in both chambers. Upon closing of the second chamber a reference pressure corresponding to the desired tire pressure will prevail therein. Any reduction of the tire pressure relative to the reference pressure will cause the diaphragm to converge towards the transparent housing portion, thus serving as an indication.

Abstract: A hand held mechanism that can be applied to a conventional tire inflation valve on a vehicle tire to facilitate a tire deflation operation. The mechanism includes a rod-like element that automatically engages a tire check valve to open said valve for tire venting purposes. The mechanism also includes a hollow tubular called wall structure adapted to receive the sensing head of a conventional pressure gage, whereby the progress of the tire-deflation operation can be ascertained, as necessary to properly terminate the operation at a desired tire pressure. Mechanisms of the described type can be utilized on all wheels of a multi-wheeled vehicle to permit simultaneously deflation of all vehicle tires, thereby greatly reducing the time required to achieve a total tire deflation operation.

Abstract: A system is disclosed for warning that the pressure in one tire of a pair of dual tires is more than a predetermined amount below the pressure in the other. The system comprises a device fitted to the valve stem of the outer tire and having a single air inlet and two air outlets connected one to each tire. Two pistons are subjected to tire pressures and themselves act on a lever. When the tire pressures differ, the forces on the lever are unbalanced, and the lever tilts. A trigger unit is mounted on the rim of the inner tire and linked to the lever by a stiff wire. When the wire is displaced, a spring loaded arm of the trigger unit is released. On the body of the vehicle there is a switch the operating member of which is struck by the spring loaded arm after that arm has been released. The switch is connected to a warning device in the vehicle cab.
