Abstract
Poppet valve for a piston compressor, having a valve body with a plurality of inlet ducts, wherein each inlet duct has an inlet section and an outlet section. The outlet section opens into a valve seat, wherein each inlet duct is assigned a closing element and a spring. The closing element can be moved in an axial direction (A) in such a way that the valve seat can be closed by way of the closing element. The spring has a first spring end section and a second spring end section, wherein the spring is arranged in the inlet duct and bears with the first spring end section against and is held on the inlet section of the inlet duct. The second spring end section is connected to the closing element, to bring about a pre-stressing force on the closing element, which pre-stressing force is oriented towards the valve seat.
