A plural component spray gun () is designed for spraying quick setting materials such as foams, polyurea and the like. Towards this end, the gun () is designed so as to be easily serviceable with a minimum of tools. For example, the side seal cartridges () and () may be installed and removed without tools by removing the retaining ring () and then extracting them from the fluid housing (). Those cartridges () and () are easily disassembled and cleaned. Similarly, the fluid housing () may be removed from the handle/body () by unscrewing the lock ring () by hand.

A pumping system comprises an internal combustion engine, a generator, a pumping unit and a heat recovery system. The generator is driven by the internal combustion engine. The pumping unit is powered by the generator. The heat recovery system thermally couples the internal combustion engine with the pumping unit.

Plural component proportioner

A solvent pistonshuttles between first and second positions. In the first position, high pressure air applied to the rearof the solvent pistoncloses a solvent borearound the solvent pistonand prevents passage of solvent into the mix chamber. In the second position, high pressure air is applied to the frontof the solvent pistoncausing it to retract slightly thereby uncovering the solvent bore, closing off the solvent inletand allowing a slug of solvent to mix with the purge airand pass from the solvent outletinto the mix chamber. The solvent is either self contained in the applicator or plumbed eternally to the gun.

A method of cleaning and flushing a fast-set material spray gunis disclosed which uses, in the preferred embodiment, a mixture of approximately 62.5% DMSO, 32.5% DBE and 5% water. This mixtureis non-toxic when atomized and lowers the freezing point of the liquid to below 10&#xb0; F. Because the solvent is mixed with the purge air and expelled from the gun in atomized form, it is important that a non-toxic solvent be utilized and also important that the freezing point of the mixture be low enough to allow use in colder climates without freezing.

A plural component spray gun () is designed for spraying quick setting materials such as foams and the like. A mix module () plastic material provides at least twice the life with &#xbd; the wear of currently marketed mix modules and is made of poly ether ether ketone reinforced with graphite and PTFE lubricants.

A method for controlling the damping force of a damper containing a movable object in a magneto-rheological fluid, in which a positive magnetic field is applied to the fluid to achieve an increase in viscosity (and an increase in damping force) and the polarity of the magnetic field is reversed by negative electrical energy to remove residual magnetism before reestablishing the magnetic field at a lower level to achieve a predictable decrease in viscosity (and a decrease in damping force).

Electrostatic spray gun

A spray gun is easily convertible between a number of configurations. A removable fluid insert may be placed in interchangeable (airspray and HVLP) spray heads with the fluid insert being either a pressure fed device which depends downwardly from the front end of the gun into a pressurized cup or via a connection to a pressurized fluid source or may have an upwardly directed insert which will take fluid from a gravity cup. A simple air swivel also adds ergonomic benefits.
