摘要： This foam-generating device is easily transportable, free from fluid or power supply constraints, and able to supply a foam such as viscous foam with a high (low liquid fraction), time-invariant (low liquid fraction). The gas is withdrawn compressed from a cylinder, and a fixed fraction of its flow is used to drive a pneumatic pump which draws in the foaming liquid. The foam is formed in a mixer containing free-moving solids shortly before the ejection end of the device. The mixer has highly mobile balls in a cage of much larger dimensions; it is suitable for producing foam with a high overrun. Application: decontamination and depollution of large surfaces, buildings or indoor or outdoor structures.

摘要： A sprayer includes a spray gun and a hopper. An air source provides compressed air to the sprayer to both eject fluid from the spray gun as a spray and to pressurize the hopper. The spray gun includes passages for providing compressed air to the nozzle for spraying and to the hopper for pressurizing the hopper. The spray gun further includes a relief valve for venting pressurized air from the hopper. The hopper receives the compressed air through a port in the hopper, and the compressed air assists the flow of material out of the hopper and into the spray gun.

摘要： The present invention relates to a system (10) for atomizing and ejecting a liquid (L) for a transdermal delivery. The system (10) comprises: a tank (100) for holding the liquid (L); a Venturi tube (200) comprising a longitudinal central axis (X1) and an internal passage (210) extending along the axis (X1), wherein the internal passage (210) is fluidly connected to the tank (100) via an orifice (220) defined in the Venturi tube (200), wherein the internal passage (210) comprises a converging section (230), a diverging section (240) and a throat section (250) located between the converging and diverging sections (230, 240); a cylinder (300) comprising a longitudinal central axis (X2), an end wall (310) orthogonal to the axis (X2), a circumferential wall (320) extending from the end wall (310) along the axis (X2) and an outlet hole (330) formed on the end wall (310), wherein the outlet hole (330) is fluidly connected to an inlet (232) of the converging section (230); a piston (400) arranged in the cylinder (300) so as to be displaceable in the cylinder (300) along the axis (X2), wherein the piston (400) defines an air intake space (V) in the cylinder (300) in cooperation therewith, wherein the air intake space (V) fluidly communicates with the inlet (232) of the converging section (230) via the outlet hole (330); a driving unit (500) for displacing the piston (400) in a direction in which a volume of the air intake space (V) increases; and an elastic member (600) that is deformed according to the displacement of the piston (400) and stores an elastic energy therein while the piston (400) is being displaced in the direction in which the volume of the air intake space (V) increases. The driving unit (500) comprises an elastic energy release mechanism (M) that releases the elastic energy stored in the elastic member (600), thereby causing the piston (400) to rush in a direction in which the volume of the air intake space (V) decreases.

摘要： An pressure regulating valve assembly for a pneumatic spray gun is disclosed. The pressure regulating vale component is configured inside the pressure regulating passage of the gun body, comprising a pressure regulating screw seat, a pressure regulating rod going through the pressure regulating screw seat and in threaded connection with the pressure regulating screw seat. A pressure regulating seal ring is configured between the pressure regulating rod and the pressure regulating screw seat. A clamping check ring is configured in the middle portion of the pressure regulating rod. The clamping check ring is used to limit the position of the pressure regulating rod. The inner end of the pressure regulating rod is provided with a pressure regulating valve. The position of the pressure regulating valve is limited by the split damping ring configured on the end portion of the pressure regulating rod.
