US Patent:

20060016477, Jan 26, 2006
Filed:

Jul 23, 2004
Appl. No.:

10/898416
Inventors:

Algis Zaparackas - Farmington Hills MI, US
International Classification:

G05D 7/00
US Classification:

137112000
Abstract:

A vacuum enhancing check valve for direct connection to a vehicle brake booster which increases the partial vacuum provided thereto and restricts possible air back flow into the brake booster. The valve comprises a venturi for reducing the pressure of air induced to flow between a first air inlet and an air outlet by a partial vacuum at a vehicle engine's intake manifold. By significantly reducing the air pressure, the valve enhances the partial vacuum available for provision to the brake booster. The venturi is also in air communication with a second air inlet directly attachable to the brake booster such that the air pressure at the second air inlet tends toward the enhanced partial vacuum within the venturi. A valve seat and seal member within the valve are cooperative to allow air flow from the second air inlet toward the venturi, but not in the reverse direction.

US Patent:

54051703, Apr 11, 1995
Filed:

Jul 5, 1994
Appl. No.:

8/270546
Inventors:

Daniel A. Roulinson - Wyandotte MI
Algis Zaparackas - Farmington Hills MI
Assignee:

Ford Motor Company - Dearborn MI
International Classification:

F16L 3320
US Classification:

285 39
Abstract:

A fluid conduit connector assembly includes a prepositioning carrier for mounting a connector assembly upon a first fluid conduit segment, a hose clamp portion attached to the prepositioning carrier for maintaining the hose clamp in position for engagement with a second fluid conduit segment, and an axially directed activation member for maintaining the hose clamp portion in a retracted configuration prior to engagement of the hose clamp portion with the second fluid conduit segment. The hose clamp portion is movable to a non-retracted configuration when the activation member is slidingly withdrawn in an axial direction from the hose clamp portion.
