Abstract

Disposition of inlet air pressure and exhaust molding machine, especially for machine expulsive taps, which has been placed in the ejector unit, consisting of the pressure vessel and the control piston, cavity below piston pressure control, having at least two openings. In one of the openings it is plugged vent valve fast. The other opening is connected to cavity expeller through a channel and covered by a sealing element. Element seal consists of a material resistant to abrasion, it has been shaped lips and overlies the opening in the cavity under pressure.
