Appl. No.:

13/306020

Inventors:

Richard Tran - Kirkland WA, US

Assignee:

PACCAR Inc - Bellevue WA

International Classification:

B25G 1/10
H01M 2/10

US Classification:

161101, 16436, 16444, 16DIG 41, 45761, 2111051

Abstract:

A grab handle mounting assembly securable to a mounting surface includes a first mounting arm assembly securable to a mounting surface. The first mounting arm assembly defines a first male pin. A second mounting arm assembly is securable to a mounting surface and defines a second male pin. The assembly further includes a first tube having first and second open ends, wherein the first male pin is mateable within the first open end of the first tube and the second male pin is mateable within the second open end of the first tube. When the first and second mounting arm assemblies are secured to a mounting surface with the first and second male pins mated with the first and second open ends of the first tube, the first and second mounting arm assemblies impose a torsional force on the first tube.

Abstract:

An improved fuel injection pump is provided for an internal combustion engine (e.g., diesel engine), and is configured such that the secondary hand pump of the prior art can be eliminated. To achieve this result, the injection pump employs a one-way bearing or clutch on the input side of the drive shaft of the injection pump. By employing a one-way bearing or clutch, such as of the concentric roller type, or other suitable clutch, the fuel injection pump can be operated by direct coupling of the engine and the drive shaft of the fuel injection pump. Also with this configuration, once the engine is stopped, the drive shaft of the fuel injection pump can be manually driven in order to prime the system. Accordingly, by locating a one-way bearing or similar clutch device along the driveline of the fuel injection pump, the fuel injection pump can be both manually operated when the engine is shut off and automatically driven when the engine is running.

Abstract:

An interlocking pipe support includes a first interlocking bracket configured to interlock with a second interlocking bracket, wherein the first and second interlocking brackets are moveable between a first interlocking position in which they are configured to partially surround an exterior of a pipe, and a second interlocking position in which they impose a clamping load on the exterior of the pipe.

F16L 15/00

Abstract:

A coupler releasably couples a tube to a threaded port. The tube has a circumferential bead formed on one end to engage the coupler. The coupler includes a fitting with a threaded portion to threadedly engage the port. A central passage extends through the fitting and is made up of a first cavity, a second cavity, and a third cavity.The second cavity has a larger diameter than the third cavity, which is at least partially surrounded by the threaded portion of the fitting. When inserted into the central passage, the tube extends at least partially into the portion of the third cavity surrounded by the threaded portion of the fitting. The coupler further includes a retainer that engages the bead on the tube to limit movement of the tube relative to the retainer when the tube is inserted into the central passage.

Abstract:

A connector system includes a plug portion and a receiving portion. The plug portion includes a resilient retention portion at the forward end of the plug portion, a sealing member distal from the retention portion, an orientation plate rigidly connected to the plug portion, wherein the orientation plate has a frontal profile including one or more straight edges. The receiving portion includes, a hole through the receiving portion, wherein the hole has a diameter smaller than a largest diameter of the resilient retention portion, a shoulder on one side of the receiving portion that cooperates with the retention portion to fix the axial position of the plug portion in the receiving portion, a recess on the opposite side of the receiving portion, wherein the recess has a frontal shape similar to the frontal profile of the orientation plate, wherein the orientation plate fits within the recess to fix the rotational orientation of the plug portion with respect to the receiving portion.
