Title:
WATER CLEANER
Document Type and Number:
Japanese Patent JPH02198684
Kind Code:
A
Abstract:

PURPOSE: To lower a pressure drop by providing a rotary valve for changing flow passage and providing an introducing port and outflow ports on the rotary valve.

CONSTITUTION: A cartridge 3 is mounted to a faucet 10 of waterworks so as to be positioned under the horizontal pipe part of the faucet 10. A water stop face 51 of the rotary valve 5 rotating together with a layer 2 closes an inflow port 11 and the water is surely stopped by a sealing 58 enclosing the water stop face 51 when the lever 2 is directed upward. The introducing port 52 in the 1st rotary valve 5a of the rotary valve 5 faces the inflow port 11 and a discharge port 55 in the 2nd rotary valve 5b communicates with the 2nd outflow port 15 when the lever 2 is shifted one step toward the user. Then, the water flows through a communicating port 54, the discharge port 55 and the 2nd outflow port 15 and scatters by colliding against the front surface in the peripheral part of an annular partition wall member 45. The pressure drop is lowered in this way.
