摘要： A valve assembly includes a first body with a first conical valve seat and a locating bore centered about a first axis. A second body is press fit attached to the first body and has a second conical valve seat with a second axis positioned in opposition to the first conical valve seat. An elongated valve member with a centerline has an upper conical valve surface and a lower conical valve surface trapped between the first conical valve seat and the second conical valve seat. A guide portion of the elongated valve member moves in a guide bore defined by one of the first body and the second body. The first axis, the second axis and the centerline are concentrically linked via the press fit attachment of the second body in the locating bore of the first body. The valve assembly is preferably utilized as a needle control valve assembly in a fuel injector.

摘要： A fuel injector includes a barrel having an insert recess therein within which an insert is disposed. A facing surface of the insert is located opposite a base surface of the recess and forms a passage interconnecting a high pressure fuel passage and a valve bore. High pressure intersecting bores are thus avoided, leading to a reduction in structural failures.

摘要： Inclusion of a direct control needle valve in fuel injectors can allow for independent control of injection pressure and timing. Engineers have learned that it is desirable to position the control valve assembly in close proximity to the needle valve member to improve response time. However, by placing the control valve assembly in a central portion of the fuel injector, at least one fluid passage must often be routed through the electrical actuator included in the valve assembly. The present invention seeks to address this problem by providing a direct control valve assembly for a fuel injector that directs fluid around the electrical actuator without increasing the size of the fuel injector. Thus, the present invention includes an electrical actuator having an actuator centerline that is oriented at an angle, which is preferably perpendicular, with respect to a centerline of the fuel injector.

摘要： The present invention relates to fuel injectors having a free floating plunger. Traditional tappet assemblies include a plunger that is mechanically coupled to the tappet, and therefore, cannot be uncoupled over a portion of its movement during an injection event. In the event of a plunger seizure in a traditional tappet assembly, the tappet spring can be prevented from expanding, which can cause major valve train and engine damage. In addition, because the plunger in traditional tappet assemblies is moved to its upward position under the action of the tappet spring, the fuel passages can depressurize if fuel cannot refill the fuel pressurization chamber as quickly as the plunger retracts, causing cavitation bubbles. Therefore, the present invention utilizes a plunger that is not mechanically coupled to the tappet and can uncouple from the tappet during the injection event to address these and other problems related to plunger wear and failure.
摘要翻译：本发明涉及具有自由浮动柱塞的燃料喷射器。传统的挺杆组件包括机械联接到挺杆的柱塞，因此在喷射事件期间不能将其移动到其一部分运动上。在传统挺杆组件中发生柱塞塞住的情况下，可以防止挺杆弹簧膨胀，这可能导致主要的阀门系列和发动机损坏。此外，由于传统挺杆组件中的柱塞在挺杆弹簧的作用下移动到其向上的位置，所以如果燃料不能像柱塞缩回那样快速地重新填充燃料加压室，则燃料通道可以减压，导致气泡。因此，本发明利用一种柱塞，其不与挺杆机械联接，并且可以在喷射事件期间与推杆脱离，以解决与柱塞磨损和故障相关的这些和其它问题。

摘要： A workpiece internal flaw test apparatus has a frame that includes a workpiece support and a pair of transducer supports, a pair of transducers positioned on the transducer supports, a force generator, a signal generating and receiving device in communication with the pair of transducers, and a uniform contact apparatus. The pair of transducers are in alignment with one another and are adjacent opposite sides of the workpiece support. Each transducer has a contact face. The force generator is connected to the frame and is operable to push the pair of transducers toward each other with a predetermined force such that the contact faces of the transducers engage a test face of the workpiece. The uniform contact apparatus is positioned adjacent the contact face of each transducer such that the uniform contact apparatus is positionable to compensate for a misalignment between the transducer contact face and the test face of the workpiece and provide better sound coupling between the transducer and rough surface of the workpiece. A signal generating/receiving device is in communication with the transducers and provides the ability to analyze the test results to determine whether the workpiece has an internal flaw, such as a crack or void that would render it unsatisfactory for use.
