Central vacuum cleaner wall valve, hose nipple, and cleaning system
First Claim
1. A vacuum wall valve for use in association with a vacuum hose assembly having a hose nipple, the vacuum wall valve comprising:
- a) an opening for receiving the hose nipple, b) a valve member having a front surface, and c) an aperture, wherein the valve member is adapted for movement in the wall valve between a first position and a second position in response to insertion of the hose nipple through the opening and against the front surface, wherein in the first position the front surface is between the opening and the aperture, the front surface substantially encloses the opening, and fluid connection between the opening and the aperture through the wall valve is prevented by the valve member, and wherein in the second position the front surface is further into the wall valve in relation to the opening, and fluid connection is provided through the wall valve between the opening and the aperture.

Abstract
Hose nipple has longitudinal axis, distal end, and aperture. Distal end closed and in line with axis for insertion into wall valve. Aperture opens out of line with axis. Nipple and valve alignment mechanisms align nipple and valve apertures for mating. Valve member slides in valve on insertion of nipple through opening of valve against front surface of member. In first position, front surface between opening and aperture. Fluid connection through valve prevented. In second position, front surface further into valve, and fluid connection provided. Valve and nipple longitudinal retention mechanisms retain nipple. Mechanisms engaged by rotational movement. Valve and nipple rotational coupling mechanisms form rotational coupling that is manually engageable and releasable. Hose assembly has nipple, handle, and stretch hose. Handle may have turbine and generator, air causes turbine to turn and generator to generate electrical energy. Central vacuum cleaning system has vacuum source, valve, piping, and assembly.
