Abstract
A negative pressure distribution system for a textile spinning machine includes a negative pressure channel and a plurality of lines configured to deliver negative pressure to a device in the textile machine to carry out a desired task. A distributor is disposed between the negative pressure channel and the negative pressure lines. The distributor includes a housing having a variably positionable valve within the housing. The valve is positionable between a closed position wherein the negative pressure lines are pneumatically isolated from the negative pressure channel and a plurality of operable positions wherein at least one of the negative pressure lines is in communication with the negative pressure channel through the housing.
