The instant invention relates to a spinning device, in particular a spinning or winding device. The device comprises a pressure circuit with a valve installed therein to control the pressure. The valve can be actuated pneumatically. A device for rapid aeration of the valve is provided with the valve. The valve is actuated by compressed air acting upon a side of a cup seal away from a pressure chamber, causing the cup seal to close off an aeration opening. The compressed air streams past the cup seal and fills the pressure chamber, whereby a passage cross-section of the valve is reduced or closed off by means of a closing element acting upon the pressure in the pressure chamber in opposition to a restoring force. As the pressure on the side of the cup seal away from the pressure chamber is reduced, the pressure on the side of the cup seal towards the pressure chamber is increased. As a result the cup seal moves in direction of lower pressure and the aeration opening is again opened. The closing element returns in this manner rapidly into its original position under the effect of its restoring force.

Spinning device

A rotor cover designed with a sealing surface interacting with a compressed-air connection, whereby the compressed-air connection is effected via a connecting piece located between the rotor cover and the appertaining mounting plate.
