Latest Patents

One of Trefzger's latest patents is for a continuous sprayer. This device features a trigger-actuated piston assembly within a cylinder. The trigger urges the piston assembly distally in the cylinder, while a coil spring urges it proximally against the action of the trigger. The piston assembly includes a plunger portion and a hollow piston rod that extends out through a sliding seal in the cylinder's distal end, where a spray nozzle is mounted. The hollow piston rod contains a shutoff rod that works with a standard spring bias ball valve in the plunger. A seal at the distal end of the shutoff rod ensures complete shutoff when urged against a compression spring, mating with a seat in the nozzle nut. When the trigger is fully released, the plunger is forced back by the coil spring, causing the shutoff pin to contact the shutoff rod, which then seals the nozzle. This design allows for continuous spraying when the trigger is partially depressed.
