Abstract: The present invention relates to a valve combined with a water hammer arrester, including the water hammer arrester having a cylindrical casing having one side closed and the other side open, a shock-absorbing material being put into the cylindrical casing, and a piston adapted to be inserted into the cylindrical casing, the piston having packing members mounted thereon to prevent the leakage of the shock-absorbing material, wherein a drive part of the valve has an insertion portion formed by reducing the lower portion of the water hammer arrester, so that the insertion portion of the water hammer arrester functions as a spindle of the valve and a body of the water hammer arrester functions as an operating handle of the valve.

Abstract: The present invention discloses an automatic water pressure control valve balancing the temperature of mixed water, eliminating a cylinder enclosing the pressure control piston and multiple seal rings, to reduce the number of parts and to minimize the production costs of the automatic water pressure control valve, and a second automatic water pressure control valve simplifying the structure of the piston within the cylinder to enhance productivity of the automatic water pressure control valve, and comprising additionally the backflow cutoff valves in each of the hot water outlet and the cold water outlet to prevent back flows of water. Therefore, initial control of water pressure is easy because the piston is always placed in the center of the cylinder while water doesn't flow.
