Claims11
A control valve (8) for a medical suction device (1), the control valve (8) comprising an actuating element (10) connected to a valve plunger (12) movable in a valve chamber (11), wherein two or more air intake openings (16), which are open to atmosphere, are formed on the actuating element (10) and lead into the valve chamber (11), the two or more air intake openings are closable by a user and a cross-section of an air inlet defined by the two or more air intake openings is variable in fine steps by individually closing one or more of the air intake openings (16), a finger support surface (18) for manual actuation of the valve plunger (12) is formed on the actuating element (10), and the two or more air intake openings (16) are formed in the finger support surface (18);
- wherein the valve chamber (11) has an elastic, annular wall portion (26), which is fitted between the actuating element (10) and a valve body (27) that receives the valve plunger (12).
A control valve (8) for a medical suction device (1), the control valve (8) comprising an actuating element (10) connected to a valve plunger (12) movable in a valve chamber (11), wherein two or more air intake openings (16), which are open to outside, are formed on the actuating element (10) and lead into the valve chamber (11), the two or more air intake openings are closable by a user and a cross-section of an air inlet defined by the two or more air intake openings is variable in fine steps by individually closing one or more of the air intake openings (16), a finger support surface (18) for manual actuation of the valve plunger (12) is formed on the actuating element (10), and the two or more air intake openings (16) are formed in the finger support surface (18);
- wherein the actuating element (10) forms a wall area (24) of the valve chamber (11).
