Appl. No.:

10/035076

Inventors:

Daniel Smith - Spring Lake MI
David Eickholt - Kentwood MI
Michael Weston - Lawrence MI

Assignee:

Robert Bosch Fuel Systems Corporation - Kentwood MI

International Classification:

B05B 130

US Classification:

2395851, 239 88, 2395332, 285305, 411353

Abstract:

A fuel injector unit comprises a follower assembly that includes a sleeve having an internal groove that receives a spring clip. The clip is made with a spring ring stock having a diameter less then the width of the groove so that the sleeve may be freely rotated around the retainer clip held in the groove. The retainer clip has linear portions aligned along the flat walls of a follower subassembly that receives a plunger carried by the follower assembly. The flat walls terminate at an expanded shoulder that limits displacement of the retainer clip to a fixed height of the follower assembly for shipping and handling, while permitting controlled axial movement of the follower assembly and the plunger along the aligned flat surfaces of the follower subassembly.

Mike Weston - Lawrence MI

Assignee:

Robert Bosch GmbH - Stuttgart

International Classification:

F02M 5900

US Classification:

2395332, 2395333, 2395851, 2395853, 2395855

Abstract:

A unitary fuel injector and nozzle assembly comprising a high-pressure piston pump and a cylinder body that define a high-pressure fuel pump chamber. An injector nozzle assembly is in fluid communication with the pump chamber and is held in place by a nozzle nut detachably secured to the cylinder body. A nozzle valve assembly includes a spring located in a spring cage within the nozzle nut. A control module is assembled between the cylinder body and the spring cage, the module including a module body having a valve chamber that receives a control valve and a stator assembly as separate and removable elements of the module whereby the stator assembly, the nozzle valve assembly and the control valve can be changed independently of the other elements of the injector to meet various operating requirements.

Appl. No.:

11/942628

Inventors:

Oberlin Jeff - Fruitport MI, US
David W. Eickholt - Kentwood MI, US

Assignee:

Tennant Company - Minneapolis MN

International Classification:

A47L 11/29

US Classification:

15320, 15322, 15401

Abstract:

A squeegee blade assembly and method of use for a floor surface maintenance machine. A blade/guide subassembly is inserted into a channel of a scrub head prior to operation. During operation, the subassembly is retained with the channel via friction and/or protruding structures. During a blade exchange procedure, the subassembly is retracted from the channel prior to separation of the blade from the guide. Interaction with a protruding structure within the channel signals to an operator that the subassembly has been properly positioned.

International Classification:

F02M 5100

US Classification:

2395851, 239 88

Abstract:

An electromagnetic actuator for a control valve module in an engine fuel injector, the module being a replaceable, independent element of the injector. The actuator has a stator with electromagnetic coil windings on a bobbin located within the control valve module. An armature is connected to a control valve in the module. The bobbin supports and precisely positions connector pins for the coil windings for registry with an external electrical wire harness.
