Title:
PRESSURE DEVICE FOR SUPPLY WATER PRESSURE
Document Type and Number:
Japanese Patent JPH08270603
Kind Code:
A
Abstract:

PURPOSE: To perform a direct supply of water without using an elevated water tank relating to supply of water to a building high story, by pressurizing a supply water pressure by using a compressed pressure in a pressure mechanism which performs action of sucking water into a cylinder chamber in a spread side and of delivering water with which inside the cylinder chamber is charged in a contracted side.

CONSTITUTION: In a switching valve 4, by a solenoid 41 of performing switching operation by a signal alternately fed from switches 35, 35, supply water from a city water main pipe W is introduced to one small diametric cylinder chamber suction port 33a and to one suction/discharge port 31a of a large diametric cylinder chamber 30. A waterway of opening the other suction/discharge port 31b of the large diametric cylinder chamber 30 to a discharge side is successively switched to a waterway of introducing supply water from the city water main pipe W to the other small diametric cylinder suction port 33b and to the other suction/discharge port 31b of the large diametric cylinder chamber also to open the one suction/discharge port 31a of the large diametric cylinder chamber to the discharge side. The switches 35, 35 are formed into a liquid pressure transmitting mechanism such as a small diametric pipe connected to an end part of small diametric cylinder chambers 32a, 32b.
