Abstract: A foam spray gun is illustrated in which a third hose is attached to the gun for the application of either a liquid or a gas.

Abstract: The invention described herein generally pertains to in-situ applications of liquid chemicals mixed and dispensed as a spray or a foam and more specifically, to in-situ application of polyurethane foam or froth and the measurement of the temperature of the chemicals used therewith employing temperature-indicating one-component or two-component foam gun nozzles and/or at least one temperature-indicating hose which employs at least one thermochromic material disposed within the foam gun nozzle and/or hoses.

Abstract: A metering component for a two-component dispensing gun includes a first metering rod and a second metering rod. The first metering rod includes a first tip section at one end that terminates into a first intermediate sealing section. The first intermediate sealing section terminates at a first base section at an opposite end of the first tip section. The second metering rod includes a second tip section at one end terminating in a second intermediate sealing section, wherein the second intermediate sealing section terminates at a second base section at an opposite end of the second tip section. The first metering rod is interconnected to the second metering rod at the first base section and the second base section.

Abstract: A variably tensionable check valve with a first end and a second end that includes a housing, a tension adjuster, a resiliently deformable elastic member, and a flow restriction member biased in a closed position. The housing includes a first portion, a second portion, and first and second passageways with a transition portion therebetween. The second portion includes at least one peripherally extending raised rib and a second internal passageway. The surface area of a cross-section of the first internal passageway is greater than the surface area of a cross-section of the second internal passageway. The tension adjuster, the elastic member, and the flow restriction member are located within the first internal passageway, wherein the tension adjuster secures the elastic member and the flow restriction member within the first internal passageway, and wherein rotational movement of the tension adjuster modifies the biasing force of the elastic member.
