A valve assembly configured for use with an inflatable product, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. The valve assembly includes a first valve component that serves as an opening for inflation and/or deflation of the inflatable product, and a second valve component that serves as an opening for deflation or decompression of the inflatable product.

A repeatable use valve in a tennis ball that uses a common sports ball inflation needle inserted into and through the valve to increase or decrease the pressure inside the ball. The increase or decrease in pressure will cause the ball to have respectively higher or lower bounce. The valve can be installed in new tennis balls at the time of manufacture. The valve can also be installed in used tennis balls, including used tennis balls that have lost some or all of their original factory pressure.

A valve for an inflatable device is disclosed. The valve includes a base configured to seal to a fluid impermeable wall of a bladder of the inflatable device, a cap including a rim, and a seal. The bases defines an orifice for exhausting fluid from an interior of the inflatable device and a sealing surface. The rim can include a generally circular peripheral region including at least one rib located about an underside of the peripheral region and a cavity defined in part by at least one wall located radially inward of the rib. The seal can include a first end region secured to the cap within the cavity between the at least one wall and the at least one rib and a second end region configured to move with the at least one first end region secured to the cap.

An adapter connects to a valve to convert the valve to a uniform configuration for connection to a pump. In one application, a conventional Schrader or Presta valve has an adapter to convert the valve to a uniform configuration for connection to a pump. An attachment head of a pump engages and creates a seal with the adapter and has a release mechanism to disengage the attachment head from the adapter.

A multifunctional external inflating valve and a mounting method for a loading device are disclosed. An inflating valve body of the inflating valve includes a three-way through main body through from a side surface by a side surface connecting part connecting a loading device. A valve core is arranged in an axial middle hole. A hole cavity is formed in the front portion of the axial middle hole and connected to an original tire inflating valve. An outer conical surface is arranged on the front portion of the valve core. The front portion, comprising the outer conical surface, of the core protrudes out of the front end of the hole cavity of the main body. An core conical surface sealing rubber pipe is mounted on the outer conical surface of the core and seals the core and a conical hole sealing surface of a tire inflating valve inner hole cavity.

An inflator valve connector includes a housing, a connection assembly, a valve seat, and a pushing member. The connection assembly is rotatably arranged in the housing and includes a first connection hole adapted to connect a Presta valve and a second connection hole adapted to connect a Schrader valve. The valve seat has a first abutting portion faced to the first connection hole and adapted to abut a lock nut of the Presta valve, and a second abutting portion faced to the second connection hole and adapted to abut a valve core of the Schrader valve. The pushing member removably contacts the connection assembly and has a pushing portion adapted to enter the housing via the first connection hole and to push against the first abutting portion, causing the valve seat to move relative to the housing and to close to the second connection hole.

A valve core includes: a core body screwed with a female screw part of a core mounting hole and formed of a seal ring, and a support base including a male screw part and a sleeve part; a shaft part penetrating through the support base; a valve body provided at a tip of the shaft part; an overhang part provided at the sleeve part so as to laterally overhang from a basal end of the sleeve part; a plate part provided at the support base so as to project to a basal end side from the basal end of the sleeve part and having a pair of flat tool abutting surfaces; and a shaft receiving hole penetrating through the plate part. The seal ring has a shape of a ring whose cross-sectional shape is quadrangular and the overhang part and the seal ring abut on each other by their surfaces.
