  • the discharge valve according to the invention functions as follows: Whenever the toilet is used and the content in the toilet bowl needs to be discharged, a button (not shown) on the starter device 2 (see Fig. 1) is pushed in and opens for vacuum from the discharge line 22/vacuum hose 12 to the control valve 4 via vacuum tube 6 and 7.
  • the discharge valve is at this time closed and the gate valve body 24 with the packing body 11 is in a lower closed position as shown in Fig. 2.
  • Air is now, as the starter button is pushed, immediately evacuated from the chamber 43 of the control valve 4 whereby the pistons 42, 22 will move towards one another and the atmosphere air intake valve 9 is being closed while and a vacuum source closure valve 10 is opened.
  • Air form the upper membrane chamber is then evacuated via the vacuum bore 15 and at the same time air is evacuated from the space between the packing body 11 and gate valve body 24 such that the packing body contracts (shrinks) to eliminate friction between the packing body and the valve seat 27 and through-flow opening 26 (see Fig. 3).
  • the seat valve body now opens speedily to a full open position as shown in Fig. 3 and the content of the toilet is evacuated through the opening 26 (not further shown).
  • the opening time for the gate valve body 24, i.e. the time camber 43 of the control device 4 is subjected to vacuum, is preset by the starter device 2, not further explained) to ensure complete emptying of the toilet, usually 3 - 4 seconds.
  • the starter device 2 cuts off the vacuum to the chamber 43
  • the pistons 42, 22 of the control device are move outwards by the helical spring 45 whereby the vacuum source valve closes while the air evacuation valve 9 opens to evacuate air from the upper chamber 23 of the discharge valve 1.
  • the helical spring 19 forces the gate valve body 24 with the piston 36 downwards to a closing position as shown in Fig. 2.
  • the packing body 11 expands returning to its original shape as air again enters the space between the packing body and gate valve body through the air opening 16, thereby tightly pressing against the valve seat 27 sealing off the flow-trough area 26 of the valve.
  • the water flushing valve 57 is still open 5 - 6 seconds after the closing of the discharge valve. Thereafter the vacuum is cut off by the starter device 2 (Fig.1 - function not further shown or explained) and the piston 52 of the flushing control device 5 is forced downwards displacing the power arm 53 which in turn forces the valve body 51 towards the valve seat 56 and thereby closing off the water supply.
