Abstract
A valve (10) such as an outlet valve of a dispenser comprises a valve body (30) movable from the closing rest position in opposite directions to effect two open positions, namely e.g. one for venting a pumping chamber (8) and the other for discharging the liquid medium from this pressure chamber (8). Thereby the valve (10) opening as a function of pressure may also be automatically opened when a relative low pressure is predominant.
