An injector for introducing a fluid includes a main body designed as an insert and including a first tool contact surface for an injection-molding tool and a second tool contact surface for the injection-molding tool; and an injection-molded housing that completely encloses the main body on at least one portion of the main body, the injection-molded housing including at least one first opening that extends linearly towards the main body.

The disclosure relates to an atomizer for the application of a multi-component paint, with a master paint connection, a hardener connection, a mixer, a hardener line leading in the atomizer from the hardener connection to the mixer, a master paint line, which in the atomizer leads from the master paint connection to the mixer, and with a main valve for controlling the paint delivery, the main valve being arranged downstream of the mixer and controlling the flow of the multicomponent paint to an application element, in particular to a rotatable bell cup. The atomizer according to the disclosure is characterized by a first return connection for returning the multicomponent paint from the atomizer to a return system. For this purpose, the atomizer has a first return line which branches off in the atomizer between the mixer and the main valve and opens into the first return connection.

A foam sprayer includes a body defining a channel, a nozzle, and an adapter configured to releasably attach to a first fluid source that provides a first fluid at a first pressure. The foam sprayer includes a connector attached to the body and configured to releasably connect the body to the adapter or to a second fluid source that provides a second fluid at a second pressure that is substantially greater than the first pressure. The foam sprayer also includes a mode selection device configured to switch the foam sprayer between a low-pressure mode and a high-pressure mode. The foam sprayer is configured to generate foam from the first fluid when the foam sprayer is in the high-pressure mode. The foam sprayer is configured to generate foam from the second fluid when the foam sprayer is in the high-pressure mode.

A water spray gun for control of an outflow of water and adjustment of the amount of the outflow is revealed. The water spray gun includes a handle portion, a pipe portion connected to the handle portion and used for spraying water, and a control device arranged at the position where the pipe portion meets the handle portion. The control device comprises a press part and a rotary control member. The amount of the water outflow is controlled by the rotary control member. The amount of the outflow sprayed out from the pipe portion at respective stages is continuously controlled and regulated by the control device.

A liquid discharge apparatus to discharge liquid to apply the liquid to an object includes a head, a mover, a rotator, and processing circuitry. The head has a nozzle surface in which a plurality of nozzle rows each including a plurality of nozzles to discharge the liquid are arranged. The mover relatively moves the head and the object in each of a first direction and a second direction orthogonal to each other along the nozzle surface. The rotator rotates the head along the nozzle surface. The processing circuitry controls the relative movement to correct unevenness of a nozzle interval between the plurality of nozzles along the second direction caused by an inclination between the first direction and a third direction when the head is rotated. The third direction is a direction in which the plurality of nozzles are arranged in each of the plurality of nozzle rows.

A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

A spray gun, which contains: a coating liquid nozzle configured to discharge a coating liquid from an outlet; and a flow channel forming member configured to surround an outer perimeter surface of the coating liquid nozzle to form an air flow channel, through which atomizing air passes, between the outer perimeter surface of the coating liquid nozzle and the flow channel forming member, wherein the spray gun is configured to atomize the coating liquid with the atomizing air to spray the atomized coating liquid to a coating target, wherein a gap T of the narrowest part of the air flow channel is 0.48 mm or smaller, and wherein a ratio T/L of the gap T to a distance L from the narrowest part to an apical surface at which the outlet of the coating liquid nozzle is open is 0.60 or greater.

An electrically powered, compact, ready to use sprayer that includes a main housing. When the sprayer is used in conjunction with an electric motor, self-feeding undulating tentacles, a spinning element, a spherical boot, spherical boot outlet, feed hose, and an extended wand outlet it is able to pump low and high viscosity fluid, create a liquid spray, and dispense fluid in the forward direction with very few moving parts and minimum energy.

The disclosure concerns an applicator (e.g. printhead) for applying a coating agent (e.g. paint) to a component (e.g. motor vehicle body component), having at least one nozzle row with a plurality of nozzles for dispensing the coating agent in the form of a jet in each case, the nozzles being arranged along the nozzle row and in a common nozzle plane, and having a plurality of actuators for controlled release or closure of the nozzles. The disclosure provides that the individual actuators each have an outer dimension along the nozzle row which is greater than a nozzle distance along the nozzle row.

A fluid applicator configured to receive a pressurized fluid includes a pressure vessel configured to receive the pressurized fluid from a fluid delivery line. The pressure vessel includes a valve chamber configured to receive a valve assembly, a filter chamber configured to receive a filter assembly, and a fluid delivery line fitting configured to be coupled to the fluid delivery line. The fluid applicator further including a tip assembly coupled to the pressure vessel and configured to atomize the pressurized fluid.
