A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

A modular fluid delivery assembly is provided. The modular fluid delivery assembly comprises a fluid conduit. The modular fluid delivery assembly also comprises an electrical heating element disposed within the fluid conduit. The electrical heating element is configured to provide a heat source within the fluid conduit. The modular fluid delivery assembly also comprises a connection assembly, located proximate an end of the modular fluid delivery assembly, coupled to the heating element and the fluid conduit. The connection assembly is configured to provide a hydraulic coupling to the fluid conduit, and to provide an electronic coupling to the electrical heating element.

Internally heated modular fluid delivery system

A mixer for a plural component spray gun is presented. The mixer has a mixer body comprising a mixing chamber with an outlet. The mixer also has a first fluid component inlet, coupled to a first fluid conduit, configured to introduce a first fluid component into the mixing chamber. The mixer also has a second fluid component inlet, coupled to a second fluid conduit, configured to introduce a second fluid component into the mixing chamber. The first and second fluid component inlets are offset with respect to a centerline of the mixing chamber and positioned such that a first fluid flow from the first inlet is directed toward the outlet, and a second fluid flow from the second inlet is directed toward the outlet.

Mixer design for a plural component system

An exemplary plural component heater assembly includes a plurality of heater modules each having a plurality of bores forming at least a first component path and a second component path, and at least one heating element receptacle configured to receive a heating element for heating the first and second component paths.

A modular paint pump for a paint roller having a battery operated pump in a housing supporting a paint can. A wetted parts subassembly is manually removable for cleaning or service without the use of tools. The wetted parts subassembly may include inlet and outlet check valves and a piston, a seal and a pump cylinder. A cover having a siphon is secured to the paint can by an elastic cord hooked to the housing.

A liquid applicator having a collapsible liquid reservoir with an elongated outer chamber wall having a characteristic length, and a liquid delivery piston having a length substantially equal to the characteristic length, wherein the piston is telescopically received in the outer chamber wall, and an elongated intermediate chamber wall having a length substantially equal to the characteristic length and wherein the intermediate chamber wall is telescopically received in the outer chamber wall located circumferentially intermediate the piston and the outer chamber wall, wherein the liquid reservoir and piston may be telescopically expanded to either a fully expanded condition wherein the combined length of the liquid reservoir and piston is about three times the characteristic length or a partially expanded intermediate condition wherein the combined length of the liquid reservoir and piston is substantially less than half the length of the liquid reservoir and piston in the fully expanded condition.

Paint spray pump

A diaphragm pump for pumping a fluid, such as paint, includes a diaphragm separating a first chamber for accommodating and dispensing the paint from a second chamber for accommodating a drive fluid, and a piston that reciprocates to drive the drive fluid within the second chamber in order to flex the diaphragm to provide the pumping action within the first chamber. The diaphragm pump also includes a backing ring mounted adjacent the diaphragm that is configured to distribute the drive fluid across the diaphragm to cause a flexible region of the diaphragm to flex toward the first chamber from the outer perimeter inward toward a central pumping surface in a rolling manner. This diaphragm movement results in substantially all of the paint adjacent the diaphragm within the first chamber to move out of the first chamber when the diaphragm reaches its travel limit, and thus improves the efficiency of the diaphragm pump. Additionally, the diaphragm pump includes a drive fluid inlet formed within the piston, such that reciprocating movement of the piston results in an inflow of drive fluid into the second chamber. An input port in the piston is continuously submerged in the drive fluid when open, thereby substantially eliminating the introduction of air into the drive fluid system and thus reducing drive fluid priming problems.

Hydraulically driven diaphragm pump

A detent apparatus and method for rotatably retaining a paint spray tip and turret in a holder to permit rotation of the turret to selectively position the tip to a spraying position and a cleaning position and to selectively permit extraction and insertion of the turret with respect to the holder by actuation of the detent apparatus which is preferably made up of a protrusion and mating recess and shoulder, with a spring portion permitting relative movement of the elements of the detent apparatus to permit withdrawal and insertion of the turret with respect to the holder.
