The valve assembly comprises a first housing provided with the means for receiving the LPG and supplying the same to a second housing provided with a main stop valve of an electromagnetically opening and closing valve. The second housing is removably fixed to the first housing by a tightening bolt. Another LPG supply system is disclosed in the US patent No. 5540208, the system is provided for vapourising the LP gas received from LPG tank and to supply the same to the internal combustion engine of vehicle A catalytic burner is disposed in the release path for decomposing the fuel gas into hot steam and carbon dioxide. A release control valve is provided between the catalytic converter and the fuel tank for causing the burner and the fuel tank to communicate and to be decoupled from each other. Disadvantages of the prior art There are disadvantages associated with conventional devices. One of the main disadvantages is that the LPG cylinder in four-wheeler is in lateral position that is very dangerous and cause accident due to flow of liquefied gas in its liquefied stage. Another disadvantage is that the device is cosdy and the maintenance thereof is difficult as the construction of the device is very complicated and skilled people are required to maintain the same. Yet another disadvantage is that the conventional kits are not so efficient and some time accidents take place due to non conversion of liquefied gas in the form of vapourised gas. Still another disadvantage is that different kits of different construction are required for use in different kind of vehicles for example two wheelers and four wheelers. Object and advantages of the present invention Therefore the main object the present invention is to provide a LPG conversion kit which obviates the disadvantages associated with the conventional gas conversion kits. Another object of the present invention is to provide a LPG gas conversion kit which is simple in constructions and maintenance thereof is negligible. Another object of the present invention is to provide a LPG gas conversion kit which works only when the LPG cylinder is placed in an upright/vertical position and thus the supply of LPG in the form of liquefied form does not occur at all. Yet another object of the present invention is to provide a LPG gas conversion kit which is less in cost and can be manufactured indigenously and easily.
