Description
Systems to Reduce Vibration Damage in Hydrogen Generating Apparatus B ack rg ound Hydrogen Generating Systems may be used on a vehicle to generate hydrogen gas for supplementing the vehicle's fuel supply for fuel economy, to reduce emissions and/or to increase engine performance.
A reality of the use of such hydrogen generating systems is that they undergo significant vibration when on the vehicle. It has been determined that such vibration may cause premature component failure in a hydrogen generation system.
Summary A hydrogen generating system according to one aspect of the present invention includes a container for accommodating electrolyte; electrodes including at least one anode and at least one cathode configured to be capable of generate hydrogen gas by operation in the electrolyte; a component connector connecting a first member of the apparatus to a second member of the apparatus; a shock absorber positioned adjacent the component connector to damp vibration between the first member and the second member along the component connector.
It is to be understood that other aspects of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein various embodiments of the invention are shown and described by way of illustration. As will be realized, the invention is capable for other and different embodiments and its several details are capable of modification in various other respects, all without departing from the spirit and scope of the present invention. Accordingly the drawings and detailed description are to be regarded as illustrative in nature and not as restrictive.
Brief Description of the Drawings DMSLeeal\045401\00097\ 2261114,1 Referring to the drawings, several aspects of the present invention are illustrated by way of example, and not by way of limitation, in detail in the figures, wherein:
Figure 1 is a schematic view of a component connector according to one aspect of the present invention.
Figure 2 is a perspective view of a pair of electrolysis electrode assemblies including electrode terminal connections according to one aspect of the present invention. The electrode assemblies are shown with their side cell container removed, but mounted on the housing base.
Figure 3 is an exploded view of the left hand electrode assembly of Figure 2.
Description of the Invention The detailed description set forth below in connection with the appended drawings is intended as a description of various embodiments of the present invention and is not intended to represent the only embodiments contemplated by the inventor. The detailed description includes specific details for the purpose of providing a comprehensive understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details.
Referring to Figure 1, a hydrogen generating system according to one aspect of the present invention includes a container for accommodating electrolyte;
electrodes including at least one anode and at least one cathode configured to be capable of generate hydrogen gas by operation in the electrolyte; a component connector connecting a first member of the apparatus to a second member of the apparatus; a shock absorber positioned adjacent the component connector to damp vibration between the first member and the second member along the component connector.
DMSLegal\045401\00097\ 2261114v1 2 The component connector, the first member and the second member may be any of various parts of the hydrogen generating apparatus. In one embodiment, the component connector may for example be an electrode terminal, the first member may for example be a portion of the housing and the second member may for example be a portion of an electrode. In such an embodiment, the terminal may extend from the housing to the electrode to thereby conduct electricity from a source to the electrode. As such, in such an embodiment, the terminal at one end may extend through and have a mounting connection to the housing and at its opposite end may be connected to the electrode.
Vibration in such an arrangement may either jeopardize the terminal's mount in the housing which may cause the terminal to become loosened from the housing, may cause leakage between the terminal and the housing, etc. Alternately or in addition, vibration may cause the terminal to become disconnected from the electrode or may cause either or both of the terminal and the electrode to wear and fail adjacent the connection therebetween.
In such an embodiment, for example as shown in Figures 2 and 3, a shock absorber may be positioned to damp vibration along the terminal. In the illustrated embodiment, a spring is positioned about the terminal to apply force axially outwardly from the spring at the two ends of the terminal. The spring tends to hold the terminal in tension between its mount in the housing and its connection to the electrode and damps vibration of the terminal. Of course, while a spring is shown, that spring could be replaced by an elastomeric sleeve about or adjacent the terminal.
Although the present invention is illustrated through the specific example of a terminal connection, it is to be understood that the invention can be applied to other connections in a hydrogen generating apparatus that are susceptible to damage as a result of vibration.
Such connections may include, for example, the connection between filter components, installation legs, etc.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to those DMSl-egal\045401 \00097\ 2261114,1 3 embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein, but is to be accorded the full scope consistent with the claims, wherein reference to an element in the singular, such as by use of the article "a" or "an" is not intended to mean "one and only one" unless specifically so stated, but rather "one or more". All structural and functional equivalents to the elements of the various embodiments described throughout the disclosure that are know or later come to be known to those of ordinary skill in the art are intended to be encompassed by the elements of the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 USC
112, sixth paragraph, unless the element is expressly recited using the phrase "means for" or "step for".
