Abstract

A pneumatic valve apparatus for a compressed air device, including: a pneumatic solenoid valve having a housing body with a supply channel, a consumer channel and a vent channel, wherein the housing body surrounds a valve chamber, in which a valve body can be moved along a valve axis counter to the force of a valve spring by an actuator relative to a vent valve seat leading to the vent channel and relative to a supply valve seat leading to the supply channel, wherein in a first position, the valve body opens the valve chamber and the vent valve seat leading to a vent channel, and, in a second position, opens a supply channel leading to the supply valve seat and the valve chamber, wherein the housing body comprises a diffuser, which adjoins the vent valve seat leading to the vent channel.
