<p>A pressurized gas can assembly (20) comprising a pumping device includes a pump cylinder (34) having a port (35a). The pump device also includes structure for compressed air in the cylinder (34) and venting the compressed air into the gas can assembly (20) and structure for transferring the liquid in the gas can assembly (20) out of the gas can assembly (20). An anti-siphon valve (56) is positioned in the transfer device, which, when activated prevents siphoning of the liquid. A pressure relief valve (49) is provided for relieving pressure in the gas can assembly (20) when it exceeds the predetermined level.</p> |
