A surface treatment device for applying a surface treatment to an inner surface of a hollow engine shaft includes a supply of a surface treatment agent and an elongated rod extending from a proximal end to a distal end. The elongated rod has an inner passage extending from the proximal end to the distal end. The proximal end has an inlet fluidly coupled to the supply of the surface treatment agent. The inner passage terminates at an outlet at the distal end. The elongated rod is insertable inside the hollow engine shaft. An applicator is disposed at the distal end of the elongated rod adjacent the outlet. The applicator is engageable with the inner surface of the hollow engine shaft for applying the surface treatment agent from the supply of the surface treatment agent to the inner surface of the hollow engine shaft.

Portable hybrid system for application of any material of drywall compound material, paint material, and texture material by the hybrid system via any of a plurality of material expulsion outlet ports, comprising: a pressurizable hollow tank for carrying material, at least one air compressor for pressurizing the material from the tank, an optionally attachable paint roller subsystem, an optionally attachable paint sprayer subsystem, an optionally attachable drywall compound applicator subsystem, an optionally attachable texture applicator subsystem, and an optionally attachable edge-cutting porous paint pad subsystem, enabling a plurality of workers to apply a given material from a single tank of the material.

There is disclosed a paint application system. The paint application system comprises an applicator for applying paint to a surface to be painted and a supply unit in fluid communication with the application and having a positive pressure source for supplying paint to the applicator and a negative pressure source for supplying a negative pressure to the applicator. Both the paint and the negative pressure are supplied to the applicator at the same time such that any excess paint present at the applicator during the application of the paint to the surface to be painted is collected by the negative pressure at the applicator and removed from the applicator.

A paint applicator, kit and methodology for using the same is disclosed. For example, a paint applicator that allows a user to load a desired amount of paint, such as a water based or other low VOC paint, into the paint applicator and an advancement mechanism that dispenses paint at a rate controllable by the user is disclosed. The advancement mechanism can include a system that translates a rotational force applied to an end cap of the applicator into a linear force that advances a piston which in turn applies paint to an applicator portion. The paint applicator may be reusable or may include a ratchet system that allows for only one time use. The methodology and kit can incorporate a syringe for loading paint into the paint applicator, thus reducing the loss of paint through spilling.

The subject matter discloses a faucet inserted into a paint port of a painting apparatus to control flow of paint removed from the painting apparatus, the faucet comprising an external mold rotatably insertable into a paint port of a painting apparatus; wherein said external mold is spiral; an internal mold insertable into the external mold; a faucet valve to control flow of paint from the paint apparatus.

An apparatus for dispensing a fluid comprises a housing and a resilient liner adapted to hold the fluid disposed in the housing. A fluid transfer mechanism is in fluid communication between the liner and an applicator assembly mounted on the housing for dispensing the fluid on the skin of the user. The applicator assembly includes an actuator movable relative to the housing so as to activate the fluid transfer mechanism when the actuator is reciprocated. A fluid delivery element is held in contact against skin of a user for applying the fluid onto the skin. The fluid delivery element is supported on the actuator to be movable together with the actuator by varying contact pressure with the skin. Each movement of the actuator generates continuous negative pressure within the liner for drawing fluid through the fluid transfer mechanism and collapsing the liner.

A spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head attached to the adapter body is attached at the upper portion of the adapter body. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper portion and the lower portion of the adapter body.
