Piston compressor with poppet valve and poppet valve

摘要

The piston compressor poppet valve (1) includes a catcher (3) and a valve body (2) having a plurality of suction ducts (2a), and each suction duct (2a) opens to a valve seat (7a). And includes a plurality of closing elements (4) movable in the axial direction (A), each suction duct (2a) is assigned one closing element (4), and the valve seat (7a) is , Arranged in the axial direction (A) opposite the associated closing element (4) and arranged so that the valve seat (7a) can be closed by the closing element (4), the spring (5) Between (3) and the closing element (4) is arranged to apply a pressurized load to the closing element (4), this pressurized load being directed towards the valve seat (7a) in the axial direction (A ) Extends to the guide (6) On the guide (6), the closing element (4) is guided so as to be movable in the axial direction (A), and the closing element (4) is connected to the closing head (4a) and the guide section. (4b), the closing head (4a) and the guide section (4b) follow each other in the axial direction (A), and the closing element (4) starts from the guide section (4b), and the guide inner space (4c) Which extends in the axial direction (A) into the closure element (4) in the direction of the closure head (4a), into which the guide part (6) also extends. The closing head (4a) has an end face (4g) extending in the axial direction (A) in the direction of the guide section (4b) up to the maximum circumference (4q), and the maximum circumference (4q) is the circumferential center point (MF). ) And the guide inner space (4c) is at least a circumferential center point (MF) in the direction of the closing head (4a). But it extends to enter into the guide internal space (4c).
