- a cylindrical container for receiving the pieces of laundry, said container including a water-permeable bottom forming a counter-pressure plate,
- a pressure plunger insertable into the container and moveable up and down with in said container, such that mechanical pressure is exerted on the laundry articles,
- said pressure plunger including a plunger plate and a pressure cushion mounted beneath the plunger plate at least a portion of said pressure cushion being fluid permeable for draining off of the water upwardly through said pressure cushion as result of mechanical pressure during downward movement of the pressure plunger, and means carried by said plunger plate for drawing off water extruded upwardly through said permeable pressure cushion, flow channel means connecting the top of said permeable pressure cushion with said water drawing off means carried by said plunger plate and means carried by said plunger plate for simultaneously feeding compressed air to said flow channel means upon completion of downward movement of the pressure plunger for flow downwardly through the permeable pressure cushion from said flow channel means.
