Abstract

297,158. Heenan & Froude, Ltd., and Walker, G. H. June 23, 1927. Heating by friction.-A hydraulic absorption apparatus for the generation of heat comprises the combination with a hydraulic absorption apparatus of a heat accumulator, the steam space in which is connected with the interior of the hydraulic absorption apparatus at a point or points at or near the centre of the vortex or vortices set up therein, where under running conditions the pressure is relatively low. A heat generator A comprising a hydraulic brake similar to that described in Specification 24949/10, [Class 106 (ii), Dynamometers &c.], has a rotor B on a shaft B' driven from a prime mover. Passages c formed in the vanes of the stator C connect the points corresponding to the centres of the vortices with annular spaces c and these are connected through a valve d by a pipe D to the steam space c of an accumulator E. Passages c<2> formed in the vanes, of the stator connect the water spaces between the vanes with annular spaces c<3> and water inlets F<1> terminating in a single pipe F. The water outlet pipe G is connected to the annular space B<2> surrounding the rotor. The pipes F, G are connected to the water space of the accumulator through a distributing valve H controlled through a. rod from a governor (not. shown). Thus when the inlet is wide open and outlet almost closed the power absorbing elements are packed full of water and the power consumed is a maximum and when the inlet is nearly closed and the outlet wide open, the power consumed is a minimum. A circulating passage J is preferably employed so that the pressure of the water supplied through the pipe F may be in excess of the pressure head between the level of the water in the accumulator E and the pressure in the device A. Suitable isolating valves f, g are arranged between the device A and the distributing valve H, valves j, j<1> between the valve H and the pump J, valves e<2>, e<3> between the valve H and the accumulator E, and a valve d in the pipe I). The distributing valve H comprises four pistons mounted in the rod K and adapted to control six parts h<1> - - h<6>. In a modification, two butterfly valves are employed one in the pipe F and the other in the pipe G and there are connected to the rod the valve H being dispensed with.
