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. Fórsálann caidéal an leacht isteach i seomra caol sula scaoiltear amach é trí pholl beag i soc an spraeire. An poll seo, nó nozzle, bailíonn an leacht chun sruth comhchruinnithe a chruthú. Is é an caidéal hiodrálacha an t-aon chomhpháirt casta sa dearadh seo, ach tá sé an-simplí a thógáil freisin.
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.
