Abstract (en)
[origin: EP1712776A1] The invention is distinguished by a valve body with a needle (22) and a cartridge (21). A recess (22) of the cartridge (21) takes in the needle (22) and comprises on one of its ends a seat plate (27). The seat plate (27) comprises a needle seat (29) for the inward opening needle (22), with the needle (22) further comprising a seat-part (24) with a sealing area that is designed to rest on the needle seat (29). At least one sack disc (39a) is fixed to the seat plate (27) and restricts the sack volume (35) in conjuction with the seat plate (27) and the seat part (24) of the needle (22). Each sack disc (39a) comprises a sack disc recess (40a) in order to modify the sack volume (35). An orifice disc (37) is arranged facing away from the sack volume (35) related to the sack disc (39a), and the orifice disc (37) comprises a nozzle (41).
