Control cover

A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.

A pump for use with a material sprayer includes a cylinder, a piston, a pump head, first and second check valves, and an elbow connected to the cylinder. The cylinder and the piston are coaxial with a pump axis. The pump head is configured to make a mechanical connection with the reciprocating drive mechanism so as to allow the reciprocating drive mechanism to reciprocate the piston along the pump axis. The elbow includes a first end, a second end, and an inner fluid channel. The first end is configured to make a fluid connection with the hopper. The second end is configured to be fixed with respect to the cylinder. The inner fluid channel extends from the first end to the second end. The pump head and the first end of the elbow are configured to make mechanical and fluid connections with a single linear motion of the pump.

A transducer, generally, has a robust, yet very flexible, steel-braid reinforced protective coverwhich is permanently assembled to a custom machined fitting. A typical pressure transduceris threaded through a SST nutand then through the cover. Bonding the transducer body to the cover's fittingcaptures the nutbetween a flangeA on the transducerand a shoulderA in the nut, allowing the nutto be freespinning yet a permanent part of the assembly

The seal () for a spray gun () is tubular in form and molded from an elastomer. The seal is placed in compression between two generally parallel surfaces () so as to seal out the fluid (such as paint) from the rod (). As the trigger () is pulled and the rod () moved rearward, the seal () bulges to accommodate the travel without exposing the rod () to the fluid.
