Abstract: A spraying gun includes a water inlet connector, a connecting member, an adjusting member, a detergent tube, a water conducting tube, and an extension pipe. Thus, the water flow rate of the spraying gun is adjusted by rotation of the adjusting member, thereby facilitating a user regulating the water flow rate of the spraying gun. In addition, the water is mixed with the detergent by rotation of the adjusting member to provide a cleaning effect.

Abstract: A fire fighting nozzle for extinguishing industrial scale fires including improved automatic pressure regulating features, enhanced educting features having central (110) and peripheral channeling (94) for foam concentrate, combined with a capacity to throw dry chemicals. The improved pressure regulating features include a spring (50) loaded double acting baffle (13), that is positioned by fire fighting fluid in communication with a hydraulic chamber, the hydraulic chamber is preferably controlled by a relief valve (42).

Abstract: A multi-layer slot coating die (A) includes a housing (30) having a cavity therein, and a divider (32) arranged within the cavity of the housing (30) such that a plurality of separate channels are defined therein. The channels have elongated openings on an output side of the die (A) from which layers (10, 12) of coating material are extruded, and an ultrasonic transducer (44) is mechanically coupled to the divider (32).

Abstract: The spray gun has an air cap that generates a spray mixture of liquid and air. The air cap includes a fluid valve for controlling the delivery of liquid and a separate air valve in the body of the spray gun is provided for controlling delivery of air. A control mechanism assembly for both of the valves is located axially within a central bore extending substantially the length of the spray gun. The control mechanism is actuated by means of a cam and follower arrangement with the cam surface provided on the rear of a manually operable trigger. The fluid valve is fully adjustable separately from the air valve but the control mechanism assembly includes a common control member that is in engagement with the control mechanism and operates both the fluid and air valves.

Abstract: The present invention relates to polyurethane foam spray guns and disposable, attachable nozzles. The spray gun has at least two barrels and metering chambers containing continuous passageways defined by inner bores. Each inner bore can have at least one ramp-shaped slot for controlled metering of a resin. Within each barrel and metering chamber is a plunger. At the front end of the plunger but not the tip is an O-ring that aids in the control of the metering of each resin. At the mid-section of the plunger is at least one O-ring that aids in the prevention of leakage within the spray gun. Both the plunger tip and the discharge opening of each barrel/metering chamber are narrowed/conical. The nozzle contains a one-way valve to prevent the crossover of the resins. The nozzle's tip has different shapes depending on the structure of the foam product desired.

Abstract: A fuel injector for an internal combustion engine includes a first injection valve having a first valve element that can be displaced in an axial direction and a first actuating device located axially downstream from the first injection valve to actuate the first injection valve. The fuel injector also has at least one second injection valve with a valve element that can be axially displaced and a second actuating device to actuate the second injection valve. The second actuating device is mounted axially downstream from the first actuating device in the valve housing, and the second actuating device to actuate the second injection valve is coupled to the latter by an actuating element, in the form of a cage-like arrangement, mounted in the valve housing in such a way that it can be displaced axially and bypasses the first actuating device.
