Title: Flow control circuit capable of joining fluid flows automatically
Inventor: MASUDA KENJI
IPC: F04B23/04
Filed: 1981-07-13
Abstract: PURPOSE:To join the flows of fluid discharged from a plurality of pumps automatically, by by-passing a circuit of pressure control valves from a main fluid passage extended between a pump and a throttle valve, connecting a circuit of other pumps and  check valves to said main fluid passage, and providing pressure compensating valves in  respective fluid passages branched from the passage extended between said other  pumps and the check valves. CONSTITUTION:While the opening of a throttle valve 3 is small, spring pressures DELTAP1,  DELTAP2, DELTAP3 of by-pass pressure compensating valves 5, 12, 16 associated respectively with  a first to a third fixed displacement pumps 1, 7, 17 hold the following relationship; DELTAP1>DELTAP2>DELTAP3. Therefore, the differential pressure on the opposite sides of the throttle valve 3 is determined only by DELTAP1 and only the pump 1 is coupled operatively with  a main fluid passage 4. Subsequently, when the differential pressure on the opposite sides of the valve 3 becomes lower than P2 as its opening is increased, the pump 2 is  also set into operation in addition to the pump 1, so that fluid discharged from these  two pumps is passed through the main fluid passage 4. Similarly, when the opening of  the valve 3 is further increased, the pump 3 is also set into operation together with the  pumps 1, 2.

Title: Faucet
Inventor: MATSUO SHINSUKE
IPC: F16K25/04
Filed: 1993-04-13
Abstract: PURPOSE:To facilitate manufacture of a faucet and to improve heat insulating ability by a method wherein the inlet and the outlet of an internal member are communicated with a gap and a layer formed of resin is formed at least at a part of the inner peripheral surface of an external member. CONSTITUTION:A covering layer 54 formed of polytetrafuloroethylene is formed on the inner peripheral surface of an outer casing 50. Thus, the cavitation damage of the outer casing 50 owing to cavitation is prevented from occurring. Further, since the surface of the covering layer 54 is smoothened, there is no need for secondary machining, such as grinding and polishing, of the part, with which a sealant makes contact, of an O-ring. Further, when the thickness of the covering layer 54 is increased, since resin has insulating ability, the outer peripheral surface of the outer casing 50 is prevented from being heated. This constitution causes a water flow passage 55 to form a hot water flow passage, resulting in the increase of the degree of freedom of a design of variation in a position between a mixing valve cartridge 70 and a switch valve cartridge 150.
