A valve with elastic deformation and having a tubular core adapted to form an internal air passage from an external longitudinal end of the valve to an internal longitudinal end, the tubular core being at least partially surrounded by a sleeve of elastically deformable material and having a bulb shape widening in proximity to the internal longitudinal end of the valve and ending in an internal longitudinal bulb end. A cup made of rigid material includes a first portion facing an internal longitudinal bulb end face and at least one second portion curved away from the internal longitudinal end of the valve, the cup serving as a way of limiting deformation of the bulb.

A tire monitoring system with mounting features on a housing provide for positioning through a wide range of angles. Accordingly, the system can be positioned on a variety of wheel rim/valve combinations. The tire monitoring apparatus includes two opposed wings provided on the housing to facilitate the range of positioning angles at which the housing can be positioned with respect to a valve base. Each opposed wing has a same exterior surface radius of curvature and the wings are clamped between a base plate and a clamp plate at the desired angle.

Disclosed is a monitoring device used for acquiring monitoring data of a tire, which includes a housing, the housing comprises an upper housing and a lower housing, a cavity is formed between the upper housing and the lower housing; a circuit board, the circuit board comprises a first surface which is a side of the circuit board close to the upper housing, and the circuit board is installed in the cavity; a power supply, the power supply is arranged on one side of the circuit board; and an antenna assembly, the antenna assembly includes a first antenna, the first antenna is wound on the circuit board for at least three turns, and the first antenna is used for transmitting a radio frequency signal to output the monitoring data.

A TPMS sensor with an externally replaceable battery is disclosed. The valve stem facilitates battery replacement with a valve stem core designed to removably secure a battery within the valve stem and a sensor configured with an electrical connection designed to connect the sensor to power from the battery. The valve stem has an interior cavity configured to retain the valve stem core. The battery may be at least partially retained within the valve stem. The sensor may be configured in a sensor body connected to an end of the valve stem distal from the valve stem core. The electrical connection may comprise a spring-loaded terminal configured to connect or disconnect the sensor and battery as the battery is inserted or removed from the valve stem through a valve stem end proximal to the valve stem core, permitting battery replacement without removing or deflating a tire configured with the sensor.

An inflation valve having a tubular core surrounded with an elastically deformable sleeve with a bulb widening toward the internal longitudinal end of the valve and bearing a sealing groove on its outer contour, the groove being adapted for receiving an edge of the orifice of the rim in its interior. There is a cavity between the bulb and the tubular core, having an oval-shaped outer periphery and a first spacing taken in a first direction radial to the tubular core that is greater than a second spacing taken in a second direction perpendicular to the first direction, a cross section of the inflation valve taken at the position of the cavity exhibiting symmetry with respect to the first and second directions.

A connector to connect electric circuits inside and outside the tire includes: a tubular terminal penetrating the connector attachment hole; an outer seal member surrounding outside the tubular terminal and elastically deformed by being pressed against a tire wheel to provide a seal between the tire wheel and the tubular terminal; an inner seal member filled inside the tubular terminal; one or more rod-shaped terminals penetrating the inner seal member; a plurality of communication holes formed at a plurality of positions in a circumferential direction in an intermediate portion in an axial direction of the tubular terminal; and a plurality of seal communication portions integrally formed with one or both of the outer seal member and the inner seal member and arranged in the plurality of communication holes to transmit, to the inner seal member, elastic force toward the tubular terminal by the elastic deformation of the outer seal member.

A valve system for a tire parameter monitoring system includes a valve body having an elastomeric material and a connection element. The connection element includes a first engaging device with which the connection element is detachably connected to an electronic module of the tire parameter monitoring system, a second engaging device with which the connection element is detachably connected to the valve body, and a mounting section adapted to be detachably connected to a hole in a wheel rim. A tire parameter monitoring system and a method for mounting a tire parameter monitoring system to a wheel rim of a vehicle are also provided.

A housing (4) for a tyre parameter monitoring system is provided. The housing (4) comprises two arms (10, 12) that are shaped and spaced to provide a clamp-in fitting (18) for engaging with a valve stem (34) of a clamp-in type valve (30) such that the valve stem (34) of the clamp-in type valve (30) is pivotably engaged with the housing (4) and such that the angle between the valve stem (34) of the clamp-in type valve (30) and the housing (4) is variable. The housing (4) also comprises a snap connection fitting (16) for engaging a valve stem (8) of a snap-in type valve (6). The snap connection fitting (16) is positioned between the two arms (10, 12).

A connector to connect electric circuits inside and outside the tire includes: a tubular terminal penetrating the connector attachment hole; an outer seal member surrounding outside the tubular terminal and elastically deformed by being pressed against a tire wheel to provide a seal between the tire wheel and the tubular terminal; an inner seal member filled inside the tubular terminal; one or more rod-shaped terminals penetrating the inner seal member; a plurality of communication holes formed at a plurality of positions in a circumferential direction in an intermediate portion in an axial direction of the tubular terminal; and a plurality of seal communication portions integrally formed with one or both of the outer seal member and the inner seal member and arranged in the plurality of communication holes to transmit, to the inner seal member, elastic force toward the tubular terminal by the elastic deformation of the outer seal member.
