摘要： An improved check valve assembly of the type having a relatively flexible disc member retained between relatively rigid inflow and outflow housing portions. The inflow and outflow housing portions are removably threadably interengaged to permit serviceability of the check valve and the relatively flexible disc member has a generally perpendicular stem extending into the bore of one of the housing portions to avoid misalignment of the disc with the housing. A tongue and groove means circumferentially seals the housing portions together by deforming to a common taper angle between the tongue and groove to provide sealing therebetween.

摘要： A liquid spray gun whih includes an improved flow rate control. The improved flow rate control results from a valve in the supply inlet line which can restrict the flow of liquid material from the supply container. The ability to vary the flow rate is improved because, while the electromagnetic motor is maintained at maximum electrical input power, inlet flow can be accurately regulated. Maintaining maximum input pressure ensures optimum spray performance. Finer atomization at lower flow rates can be achieved from the improved flow control system.
摘要翻译：液体喷枪包括改进的流量控制。改进的流量控制来自供给入口管线中的阀，其可以限制液体材料从供应容器的流动。改善流量的能力得到改善，因为在电磁马达保持最大电输入功率的同时，可以准确地调节入口流量。保持最大的输入压力确保了最佳的喷雾性能。可以通过改进的流量控制系统实现较低流速下的更精细雾化。

摘要： A heating coil assembly for use in an air blower device has an annular support element, a first end cap, a core having a heating coil spirally wound thereon, a sleeve surrounding the coil and core, and a second end cap. All components have a centrally disposed non-circular bore therein for receiving a heavy gauge non-circular wire retainer, swaged at one end, which extends through the entire assembly and is retained by a press washer at an opposite end. The interior of the sleeve is spaced from the coil forming an axial channel for air flow over the coil. Axial openings in the end caps form air inlets and outlets for the channel. The coil has several leads, at least one of which extends through an axial opening in one of the end caps. The heating coil assembly has a small number of components, which are easily assembled and simultaneously axially and radially positioned and retained relative to each other by the wire retainer.

摘要： A valve control mechanism for a paint spraying system provides for pressure relief prior to turn-off of the compressor. A pair of interlocking knobs, a pressure control knob and an off-prime-spray knob, are mechanically interlocked so that the compressor can only be turned on and off in a low pressure condition. When spraying has been completed, it is necessary to first operate the off-prime-spray knob to the prime position at which a cam structure opens the off-prime-spray valve for an immediate pressure relief prior to turn off of the pump.

摘要： An apparatus for applying a liquid to a surface comprising an applicator and a body member. The applicator is secured to an end of the body member, the body member defining a reservoir for housing a fluid. The body member includes a piston member for exerting a force on the fluid in the reservoir, and two channels, a first channel being in fluid communication with a channel in the applicator and a second channel being in fluid communication with an area outside the body member. The body member further including a valve for allowing fluid communication between the reservoir and either the first channel or second channel. An additional one-way valve which can be manually deactivated may be included in the second channel.

摘要： An assembly for providing a number of different size orifices for a sprayer unit, such as a hand-held paint sprayer, has an orifice plate with a number of orifices of different diameters radially disposed near a periphery of the plate. The plate has a centrally disposed pivot pin which is received in a complementary slot in the nozzle guard for the sprayer unit. The orifice plate has a like number of detents in the periphery thereof, and is held in place both within the slot and so as to align one of the orifices with the discharge nozzle for the sprayer unit, by a clip spring having angled free ends respectively received in detents on opposite sides of the orifice plate. Axial movement of the orifice plate is restrained by tightening the nozzle guard which is received by threads on the sprayer unit. When a different orifice size is desired, the nozzle guard is loosened, the orifice plate is rotated about the pivot pin to position the desired orifice in front of the discharge nozzle, and the nozzle guard is again tightened.

摘要： A hot air gun or blower of the type usable for blistering paint on a painted surface for easing the removal of paint thereof has a housing with internal brackets supporting and retaining a switch assembly, a circuit board, a motor having an impeller, a motor mount, a shroud surrounding the impeller, and a heating element. The internal brackets supporting these elements are configured so as to provide a number of air passages between the elements and the interior wall of the housing. In addition to drawing air through a rear portion of the gun, air is drawn through an annular opening in the front of the gun between the cover for the heating element and the housing. The air thus passes over the covered heating coil and is preheated before being blown by the impeller directly over the coil for primary heating. At least one wave-like flange is received between spaced interior brackets in the housing for providing a press fit of the components between the two housing halves, thus eliminating the need for mechanical fasteners for mounting the components of the gun.
