Switchable rocker arm

Mariuz, Robert M.; Keegan, Kevin R.; Charles, Peter R.; Fernandez, Hermes A.

Title: Switchable rocker arm

Abstract

A rocker arm includes an outer arm and an inner arm which selectively pivots relative to the outer arm. The rocker arm also includes a lock pin which is displaced along a lock pin axis between a coupled position and a decoupled position. The rocker arm also includes a linkage and a linkage guide which guides the linkage along a linkage axis. One surface of the linkage engages an actuator while another surface of the linkage engages the lock pin such that the linkage translates motion from the actuator to motion of the lock pin.

Switchable rocker arm

Patent Mariuz, Robert M.; Keegan, Kevin R.; Fernandez, Hermes A.

A rocker arm includes an outer arm defining a lock pin bore which is centered about a lock pin bore axis and an inner arm which selectively pivots relative to the outer arm about a pivot axis which is parallel to the lock pin bore axis. The inner arm includes a protrusion which defines an inner arm stop surface which is planar. A lock pin is disposed within the lock pin bore, the lock pin having a lock pin slot extending there into and also having a lock pin stop surface which is planar. The lock pin is displaced withinmore »« less

Dual Durameter Blow Molded Rocker Cover Design With Unique Isolation Strategy

Patent Freese, V, Charles Edwin (Westland, MI)

The rocker arm cover on a diesel engine can be formed of a rigid molded plastic material to minimize the transmission of noise into the atmosphere. Sonic vibration of the cover can be reduced by reducing the cover material stiffness. The reduced stiffness of the cover material allows the roof area of the cover to be momentarily displaced away from the cylinder head in the presence of an acoustic wave, so that the roof area is not able to develop the restoring force that is necessary for vibrational motion.

Stacked switchable element and diode combination with a low breakdown switchable element

Patent Wang, Qi [Littleton, CO]; Ward, James Scott [Englewood, CO]; Hu, Jian [Englewood, CO]; ...

A device (10) comprises a semiconductor diode (12) and a switchable element (14) positioned in stacked adjacent relationship. The semiconductor diode (12) and the switchable element (14) are electrically connected in series with one another. The switchable element (14) is switchable from a low-conductance state to a high-conductance state in response to the application of a low-density forming current and/or a low voltage.

Electronic devices containing switchably conductive silicon oxides as a switching element and methods for production and use thereof

Patent Tour, James M.; Yao, Jun; Natelson, Douglas; ...

In various embodiments, electronic devices containing switchably conductive silicon oxide as a switching element are described herein. The electronic devices are two-terminal devices containing a first electrical contact and a second electrical contact in which at least one of the first electrical contact or the second electrical contact is deposed on a substrate to define a gap region therebetween. A switching layer containing a switchably conductive silicon oxide resides in the gap region between the first electrical contact and the second electrical contact. The electronic devices exhibit hysteretic current versus voltage properties, enabling their use in switching and memory applications.more »« less

Photobiological hydrogen production with switchable photosystem-II designer algae

Patent Lee, James Weifu

A process for enhanced photobiological H.sub.2 production using transgenic alga. The process includes inducing exogenous genes in a transgenic alga by manipulating selected environmental factors. In one embodiment inducing production of an exogenous gene uncouples H.sub.2 production from existing mechanisms that would downregulate H.sub.2 production in the absence of the exogenous gene. In other embodiments inducing an exogenous gene triggers a cascade of metabolic changes that increase H.sub.2 production. In some embodiments the transgenic alga are rendered non-regenerative by inducing exogenous transgenes for proton channel polypeptides that are targeted to specific algal membranes.
