Title: Pressure balance valve mechanism for hot and cold water mixing faucet
Inventor: MIYASHITA HIROYUKI
IPC: F16K17/30
Filed: 1989-12-27
Abstract: PURPOSE:To realize the equalized water pressure, easy manufacture and reduced manufacturing cost of a pressure balance valve by making pressure on the sides of hot and cold water just before flowing into a mixing chamber act through a bypass pipe onto the backs of valve bodies, and back pressure difference between both the valve body move a piston. CONSTITUTION:Valve bodies 4a, 4b are fixed on both the ends of a lateral shaft 3 passing through a piston 2 to divide a cylinder 1 into a hot and a cold water side A and B. Cold water supply pipes 5a, 5b and discharge pipes 5a, 5b open to face on both the chambers A, B of the cylinder 1 respectively. Flow straightening chambers 7a, 7b are located the down stream side of the discharge pipes 6a, 6b, and communicates through valves 9a, 9b with a mixing chamber 8. The cold water pressure acting from the cold water supply pipe 5a on the hot water side is therefore canceled on a pressure receiving face where the valve bodies 4 are opposite to the piston 2. The hot and cold water flow down into the chambers 7a, 7b, and are led through bypass pipes 11a, 11b onto the back of the valve bodies 4a, 4b just before flowing into the chamber 8 to move the piston for balancing the pressure on the sides of the hot and cold water. Thus the simplification and miniaturization of structure and reduction in manufacturing cost can be realized.

Abstract: PURPOSE:To suppress a transient overvoltage caused by differences among the turn-on time of semiconductor elements by comparing time differences between the timing of current detecting signals at the time of turning on the semiconductor elements and the timing of a reference signal from an integrated controller and successively correcting the time differences. CONSTITUTION:Current transformers CT1-CTn for detecting currents at turning-on time are respectively installed to semiconductor elements SW1-SWn and a delay time controller 10 converts the current detecting values of the transformers CT1-CTn into digital signals and inputs the signals to a microcomputer together with a reference signal from an integrated controller 1. The microcomputer calculates the time differences between the reference signal and the outputs of the current transformers CT1-CTn and corrects delay time stored in a memory. The corrected delay time is respectively outputted to variable delay circuits DU1-DUn through bit converters BC1-BCn and correct the time differences in the turn-on time of the elements SW1-SWn connected with each other in series as signals which are obtained by delaying control signals from the integrated controller 1 by the delay time.
