331,640. Sautter, W. May 16, 1929. Direct liquid-pressure apparatus.-In apparatus for delivering inflammable &c. liquids from one or more containers C by water admitted by a pipe 21, the liquid being delivered through a pipe 23, a space 16 is arranged between the water admission valve 13 and the inlet 8 or 9 to the pipe 21, so that, when the valve 13 is closed and the apparatus is not delivering, this space is connected to low pressure, such as atmosphere, by a channel 15, thus allowing leakage past the valve 13 to escape without affecting the liquid in the container C. When the valve 13 is opened by the lever 1 for a delivery of the petrol &c. a valve 14 carried by the valve 13 closes the channel 15, so that the water passes through a non-return valve 18 and passage 19 to the inlet 8 or 9 of the water pipe 21. In another form, a non-return valve cuts off the low-pressure space from atmosphere when the water inlet valve is opened, and a spring opens it when the water valve closes. A float 32 carrying a disc 321 which lies between the two liquids is guided by the pipe 21 and a rod 24, and closes the ends 49, 52 of the pipes 23, 21 in its top and bottom positions.
