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 stem puller which comprises a length of flexible elongated member which is connected at one end to a ring and at an opposite end to an externally threaded plug. The valve stem puller is to be utilized by inserting such through a fastener nut and then through a valve stem mounting hole in a tire rim and then threadably connecting the externally threaded plug onto a valve stem of an inflating tube and then inserting the inflating tube about the tire rim and within the confines of the tire, pulling on the flexible elongated member to cause the valve stem to connect with the valve stem mounting hole in a close conforming manner. A fastening nut is then threadably mounted about the valve stem to secure such in position. The tire is then completely installed on the tire rim and the externally threaded plug is then removed from the valve stem.

Abstract: A locking valve stem cap system includes a sleeve, a valve stem cap, and a rotation tool. The sleeve is configured to threadingly engage a valve stem, with a portion of a threaded region of the valve stem protruding into a cap receptacle thereof. The valve stem cap is configured to be inserted into the cap receptacle of the sleeve and to threadingly engage the portion of the threaded region that is located within the cap receptacle. The rotation tool is configured to facilitate rotation of the valve stem cap when the outer periphery thereof is substantially surrounded by the sleeve, thereby facilitating tightening or loosening of the valve stem cap relative to the sleeve. Methods for installing and removing the valve stem cap system from a valve system are also disclosed.

Abstract: The present invention relates generally to a valve lock for use in conjunction with a valve stem contained on an inflatable tire. The device comprises a hollow tubular component that receives the valve stem. A plurality of fingers are attached to the inner wall of the tube component and grip the valve stem holding the tube component in place. Also disclosed is a locking cap that threadedly engages the fingers causing them to tighten against the exterior of the valve stem. The locking cap can only be removed with the use of a matching key that is inserted into matching indentations on the locking cap.

Abstract: Apparatus for use in co-operation with a conventional tire inflation valve which enables the pressure in a tire to be reduced to a pre-determined value in a one step process. A movable pressure regulator member, comprising a pin and slot arrangement, co-operates with a valve regulating spring to close a valve member, once the pressure in the tire has reached the required valve.

Abstract: A semi-automatic tire deflation device attachable to a tire filler valve. A spring-urged plunger mechanism within the device is alignable with the filler valve element so that manual depression of the plunger mechanism opens the filler valve to start the tire-deflation process. The plunger has differential areas exposed to pressure forces, whereby reduction of the pressure to a predetermined value allows the spring to return the plunger mechanism to its starting position, thus automatically terminating the tire-deflation process.

Abstract: The disclosure describes a valve cap which indicates the pressure within a pneumatic tire.

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.
