Abstract

A hose adapter defines a passageway therethrough and has a first connector portion and a second connector portion with the first connector portion being substantially larger in transverse dimension than the second connector portion. A transition portion is disposed between the first and second connector portions. A vacuum device is operatively associated with one of the first and second connector portions, and a hose is secured to the other connecting portion. In one embodiment, the hose adapter has a vent with an associated closure, which is designed to vary the opening in the vent and thereby alter the amount of suction created by the vacuum device. A plurality of interiorly-mounted, inwardly-projecting ribs are provided in the second connector portion to facilitate retention of a hose therein. A vacuum system employing the adapter is disclosed.

a vacuum device operatively associated with at least one of said first connector portion and said second connector portion,

a hose secured to the other of said first connector portion and said second connector portion, whereby said vacuum device is structured to draw air through said hose and said hose adapter and into said vacuum device,

a vent opening in the wall of said second connector portion for adjusting the amount of vacuum being drawn through said hose adapter assembly,

a vent closure structured to have a first position with said vent open and a second position with said vent opening at least partially closed,

said vent closure being relatively movable with respect to said vent opening,

said vent closure being secured to said hose adapter so as to permit axial movement with respect to said hose adapter between said first position and said second position, and

said vent closure being a movable sleeve disposed on the exterior of said hose adapter.

13. A hose adapter assembly comprising

a hose adapter defining a passageway therethrough and having a first connector portion and a second connector portion,

a transition portion disposed between said first connector portion and said second connector portion,
