An air valve assembly includes a housing defining an internal channel configured to receive a first member, the first member is fluidly connected to an air source, a plunger member positioned in the internal channel and configured to slide relative to the housing, a biasing member positioned in the internal channel and configured to apply a biasing force onto the plunger member, and a sealing member positioned in the internal channel and defining a first inflation aperture, the plunger member slidably received by the first inflation aperture. In a first inflation configuration, the first member is configured to form a magnetic connection with the sealing member and contact the plunger member to overcome the biasing force, the plunger member is configured to responsively slide relative to the first inflation aperture to facilitate a flow of air between the sealing member and the plunger member.

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.

The invention provides a filling device for an inflatable unit, e.g., a pneumatic tire for a car. The device is connectable to a source of air pressure and to a valve for the inflatable unit. The valve has a whistle arranged to produce an audible signal based on a flow of air in the release outlet, and to enable improved handling and sound performance, the whistle comprises a flow-path forming a first leg extending radially from the passage, and a second leg extending about the passage.

An air inflation-deflation valve includes an inflation head, a rubber seat, an inner sleeve, a shell, a first elastic part, a plug chamber, an air inlet rubber plug, a second elastic part and an air outlet rubber plug. When the air inflation-deflation valve is in use, the inflation head is inserted into a rubber chamber to contact an air port, external air enters an air passage, pushing open the air inlet rubber plug, and then enters inner chambers of inflatable products. After inflation, the second elastic part blocks the air passage. During deflation, the inflation head drives the rubber seat and inner sleeve to move, causing the air outlet port to open, thus the air is discharged through the inflation head. An overall structure of the air inflation-deflation valve is simple, easy to use, quick for inflation and deflation, and meets needs of various inflatable products.

A pressure sensitive valve core usable within a valve stem of an inflatable or pressurized apparatus and configured to automatically maintain a manufacturer's recommended air pressure within the inflatable or pressurized apparatus throughout fluctuations in temperature and elevation, and to regulate the amount of air pressure being put into the inflatable or pressurized apparatus according to a manufacturer's recommended air pressure. The pressure sensitive valve core includes a body and a spring valve mechanism including a spring designed according to Hook's Law to automatically close the spring valve mechanism against the body when a predetermined amount of pounds per square inch (PSI) is inserted into the inflatable or pressurized apparatus.
