초록 ▼

A liquid sprayer having a cylinder with a pressure chamber and a suction chamber, a hollow piston with a liquid passage therethrough and slidably fitted in said cylinder, an actuator mounted on the piston, a suction tube suspended from the bottom of the suction chamber into a liquid container, a movable valve rod vertically movable provided in the piston and cylinder and having a valve portion at the top end thereof for opening and closing the liquid passage of the piston, a compression spring for at all times urging the movable valve rod towards the direction of lifting up the piston with the liquid passage thereof being closed, and an elastic valve closely and slidably fitted onto the valve rod and adapted to establish communication between the pressure chamber and the suction chamber at its uppermost position and cut off communication therebetween at its lowermost position; whereby the passage of the piston communicating with a spray nozzle is opened when the internal pressure of the pressure chamber exceeds a predetermined level.

대표청구항 ▼

A liquid sprayer including a liquid container having a cylinder forming a pressure chamber; a hollow piston with a liquid passage therethrough and slidably fitted in said pressure chamber so as to have an upstroke and a downstroke reciprocable movement therein; an actuator having a spray nozzle mounted on said piston for moving said piston through its downstroke so as to pressurize any fluid in said pressure chamber; a suction tube extending into said liquid container and in communication with said pressure chamber; a valve rod movable with said piston and located in said pressure chamber and having a valve portion at one end thereof for opening and closing the liquid passage in said piston; a compression spring urging said valve portion toward said piston for closing said liquid passage therein and for moving said piston through its upstroke; means on said valve rod responsive to liquid pressure in said pressure chamber so as to open said liquid passage in said piston when the force exerted by said liquid pressure exceeds the force of said compression spring; and a second valve slidably fitted on said rod and located between said pressure chamber and saiD suction tube for establishing communication between the pressure chamber and said suction tube in one position and for cutting off communication therebetween in a second position, when liquid from said container is in said pressure chamber, said second valve being moved to its second position whenever and so long as the force on said valve rod exceeds that force of said compression spring so that said passage is closed when said piston is in its downstroke with liquid in said pressure chamber whereby said pressure chamber may be pressurized by said piston through its full downstroke.
