<p>The valve system (1) according to the invention comprises two valves (206, 301), an inner and an outer valve, cooperating in such a way as to control the inflow and outflow of a fluid in a fluids container such as an automobile tire. The outer valve (301) cooperates with the inner valve (206) to control the inflow or outflow of a fluid in a container. The valve system includes an energy source (4) mounted between the two valves. During normal operation, the outer valve is closed and prevents outflow from the inflatable object. When the outer valve is opened, the inner valve is also opened to enable inflow or outflow of the fluid from or into the inflatable object. When the outer valve is removed, the inner valve closes and prevents outflow or inflow of the fluid from or into the inflatable object. The energy source of the valve system can be easily exchanged without having to deflate or dismantle the fluids container. This is particularly advantageous when the fluids container is an automobile tire. Due to the fact that the energy source is located inside the valve system, it is protected against water, dirt and shocks. The energy source can be replaced without having to deflate the tire. The tire can be normally inflated or deflated due to the fact that the inner valve opens when the outer valve is opened. The valve system and the energy source form part of an electrical circuit that can be mounted onto a support plate that can be fixed to the base of the inner valve.</p> |
