It contains a trigger that activates a small water pump. The pump is linked to a plastic tube that draws the cleaned liquid from the reservoir’s bottom. Pompek şilekê dixe hundurê jûreyek teng berî ku wê di qulikek piçûk a çîçeka spreyê de derxe.. Ev qul, an nozzle, şilê berhev dike da ku çemek hevgirtî çêbike. Pompeya hîdrolîk di vê sêwiranê de yekane pêkhateya tevlihev e, lê çêkirina wê jî pir hêsan e.
Its main moving component is a piston contained within a cylindrical hydraulic chamber. There is a small spring in the hydraulic chamber. To start the hydraulic pump, it must be pulled back, allowing the piston to advance into the hydraulic chamber. When the wrench is released, the piston is pushed out of the hydraulic chamber because the piston moves compress the spring. A complete pump cycle is formed by two piston strokes into and out of the hydraulic chamber.
