Gas valve with outwardly-opening valve closure element

A gas valve (1), comprising:

• a valve body (2) which is hollow-cylindrical at least in parts and which forms a sealing seat (3) over which a gas flow path (4) is conducted;
• a reciprocating valve closure element (5) which is accommodated at least partly in the valve body (2) and which has a plate-like end portion (6) arranged outside the valve body, (2) wherein the plate-like end portion (6) interacts with the sealing seat (3);
• and
• a sleeve (7) which at least partially surrounds the valve body (2) and the valve closure element (5), the sleeve (7) including
• a cylindrical section,
• a bottom section disposed on an end side of the cylindrical section, the bottom section extending transverse to the cylindrical section, and
• an opening (10) disposed on the bottom section, the opening (10) delimited by at least one flow conduction surface (11), which is aligned at an angle to a longitudinal axis (A) of the gas valve (1),
• wherein the opening (10) is the only opening through which fluid passing through the valve body (2) exits the gas valve (1),
• wherein the sleeve (7) and the plate-like end portion (6) of the valve closure element (5) delimit an annular gap (8) which forms a throttle point in the gas flow path (4) downstream of the sealing seat (3),
• wherein a flow area through the opening (10) is greater than a flow area through the annular gap (8).
