The present disclosure relates to a spraying apparatus for spraying a liquid onto a surface. The spraying apparatus includes a tank configured to store a liquid, a neck extending from the tank and defining an opening, a pump assembly including a collar removably attached to the neck, a pump configured to draw the liquid from the tank when actuated, and a housing defining a cavity therethrough to provide a carrying handle. A wand, separate from the tank, includes a body and a nozzle assembly, having a hub rotatably attached to the body and a plurality of nozzles circumferentially arranged around the hub and extending radially outwardly therefrom. An elongate hose, having a first end and a second end, interconnects the tank and the wand by attaching to the pump assembly of the tank at the first end and the body of the wand at the second end.

A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.

A kit enables an efficient and contamination-free method of changing a resin used in a three dimensional printer from a first resin to a second resin. The three dimensional printer includes a print engine and a receptacle. The kit includes a conduit assembly and a resin container. The conduit assembly includes a fluid inlet configured to be affixed in the receptacle in an upward orientation, a pump head configured to be coupled to a motorized pump actuator in the receptacle, a first conduit coupling the fluid inlet to the pump head, a fluid outlet configured to supply resin to the print engine, and a second conduit coupling the pump head to the fluid outlet.

A portable system for washing tools is disclosed. The portable system includes a first receptacle, a second receptacle, and a filtering assembly engaged with one of the first and second receptacles. The filtering assembly is configured to engage with and communicate water from one receptacle for washing tools. The water and any mud are collected in the other receptacle. When water is depleted from a receptacle, the filter assembly is transferred to the other receptacle for reuse of the water wherein the process is repeated. The filtering assembly includes a displacement element for creating a distance between a water input port and any mud at a gravitational bottom. The filtering assembly can subsequently be moved back and forth between each receptacle for continue reuse of the water for cleaning tools.

A droplet jetting apparatus includes: a nozzle that ejects a jet of liquid droplets; a detector that detects a hand or an object in a flight path of liquid droplets from the nozzle; a pump including a suction portion for suction of liquid, and a discharge portion which is connected to the nozzle and discharges the liquid which has been sucked into the suction portion; a driver which by rotation of a cam, sucks liquid into the pump and discharges the liquid in a compressed state; and controller which actuates the driver. When the detector detects the hand or object, the controller actuates the pump by rotation of the cam, and ejects a jet of liquid in droplet form from the nozzle.

A utility bucket lid uses a common bucket lid and one or more rigid support members to strengthen the bucket lid in order to secure a pump and rigid pipe to deliver on-demand water or other fluid via a fluid manifold and valve that is connected to the rigid pipe. The rigid support member(s) support a pump having a suction hose and discharge hose and the rigid support member(s) also support a rigid pipe. The rigid pipe is passed through the bucket lid and also through the rigid support member(s). The pump's suction hose is passed into a hole proximate the top end of the rigid pipe (above the top side of the bucket lid) and exists the rigid pipe through a second hole proximate the bottom end of the rigid pipe (below the bottom side of the bucket lid). The rigid pipe holds the position of the open end of the suction hose proximate the bottom of the bucket. The top end of the rigid pipe has an open end to accept a fluid manifold, the fluid manifold having a first end and a second end, an inlet fitting, and outlet fitting, and a valve. A pump is secured to the top side of the bucket lid being fastened to the device via securement holes in the rigid support member(s). The suction hose is appropriately attached to the suction port of the pump and a discharge hose is appropriately attached to the discharge port of the pump. A hose, shower wand, and even a towel holder can also be attached to the utility bucket lid for complete hygiene in primitive settings.
