International Classification:

G05D016/02

US Classification:

137 12, 137508, 123459

Abstract:

A flow-through pressure regulator includes a retainer that secures a diaphragm relative to a seat, and includes an intermediate portion, an end portion and a base portion. The intermediate portion extends along a longitudinal axis and is fixed with respect to the seat. The end portion extends from the intermediate portion and includes a concave surface facing the seat. The regulator includes multiple flow diffusers such that the end portion includes at least one aperture having a flow axis that is oblique to the longitudinal axis so as to reduce noise due to fluid flow and/or the seat forms a passage having an increasing cross-sectional area from an inlet to an outlet.

International Classification:

F02M001/00

US Classification:

123/457000

Abstract:

A connector assembly and a method of disconnecting the connector assembly. The connector assembly comprises a first part and a second part. The first part extends along a longitudinal axis and has a protrusion that extends radially outward from the longitudinal axis. The second part receives the first part and has a wall surrounding the longitudinal axis. The wall has an inner surface generally confronting the longitudinal axis, an outer surface generally facing opposite the inner surface, a channel cooperatively receiving the protrusion; and an arm portion. The arm portion has a first surface defining a portion of the inner surface, a second surface defining a portion of the outer surface, and a bulge extending from the arm portion into the channel. The bulge engages the protrusion and maintains the first and second parts in a connected configuration. The method comprises displacing the arm portion relative to the longitudinal axis so as to disengage the bulge from the protrusion, relatively rotating about the longitudinal axis the first and second parts, relatively displacing along the longitudinal axis the relatively rotated first and second parts, and relatively separating the relatively displaced first and second parts.

Inventors:

James Wynn - Virginia Beach VA, US

Assignee:

Siemens Automotive Corporation

International Classification:

B23P019/00

US Classification:

029/239000, 029/426500

Abstract:

A tool is provided for removing a component from a fuel rail in an automotive fuel system. The tool has a pair of jaws connected to a pair of pivoting handles, which allow the jaws to be opened and closed. The jaws have an inner cavity shaped to conform to an outer surface of the component. A pair of release members are slidably mounted on an outer surface of the jaws. When the release members are moved relative to the jaws, rims on the release members contact a retention clip holding the component to the fuel rail. Contact between the rims and the clip causes the clip to disengage from a retention surface on the fuel rail, freeing the component.

International Classification:

G05D016/04

US Classification:

137/505000

Abstract:

A fuel component assembly having a fuel component disposed between a base and a cover, which prevent fluid communication to an exterior thereof. The fuel component defines at least one aperture, the base supports the fuel component and defines a passage in communication with the at least one aperture. The cover is located proximate the base. A securement having a projection and the receiver that engage to form a fluid tight seal. The projection is radially disposed about a longitudinal axis of the fuel component, and the receiver continuously engages the projection. The projection being disposed on one of the cover and the base, and the receiver being disposed on the other of the cover and the base. The fuel component assembly allows for a method of encapsulating a fuel component within a fuel supply. The method can be achieve by defining a passage within a base of an assembly; seating the fuel component within the passage; providing a cover that is contiguous with the base; and welding the cover to the base to form a hermetic seal. The fuel component assembly also provides a method of regulating a fuel supply. The method can be achieved by encapsulating a fuel component within a passage defined by a continuous wall of a housing; and controlling the pressure of fuel within the passage with the fuel component.

Abstract:

A flow-through pressure regulator includes a retainer that secures a diaphragm relative to a seat, and includes a cylindrical portion, an axial end portion and an annular portion. The cylindrical portion extends about a longitudinal axis and is fixed with respect to the seat. The axial end portion extends from the cylindrical portion and extends generally orthogonal relative to the longitudinal axis. The axial end portion includes a plurality of apertures that permit fluid communication and are selected so as to reduce noise due to fluid flow.

International Classification:

F02M069/54

US Classification:

137/508000

Abstract:

A pressure regulator includes a housing, a divider including a first valve member, and a second valve member. The housing includes an inlet and an outlet, and defines an interior volume. The divider separates the interior volume into first and second chambers, and included the first valve member, a diaphragm, and a retainer. The diaphragm extends between the housing and the first valve member. Fluid communication between the first and second chambers through the diaphragm being prevented. The retainer secures the diaphragm relative to the first valve member, and the retainer is press-fitted with respect to the first valve member. The second valve member is arranged between first and second configurations relative to the first valve member. The first configuration substantially prevents fluid communication between the inlet and the outlet, and the second configuration permits fluid communication between the inlet and the outlet.
