Patent number: 11971073Abstract: A rotary shifter assembly for changing gears in a vehicle transmission includes a shaft (16) that is rotatably supported in a housing (12) and movable between radial positions for indicating a gear change. A shift knob (10) is coupled to a first end of the shaft for actuation by a user. A plurality of flexible locking fingers (40) extend from the second end, and an overload wheel (18) is disposed about the fingers. The fingers engage the wheel to couple it with the shaft for concurrent rotation. A locking mechanism (64) engages the wheel to selectively prevent and allow concurrent rotation of the wheel and shaft during normal operation. The fingers move relative to the wheel to permit temporary rotation of the shaft relative to the wheel when a force applied to the shaft is beyond a maximum torque threshold, and automatically return to concurrent rotation with the wheel once the force is below the threshold.Type: GrantFiled: January 22, 2020Date of Patent: April 30, 2024Assignee: KA Group AGInventor: David Blank

Publication number: 20200370639Abstract: The invention is directed to a shifter assembly (1) for controlling the transmission of a vehicle. A rotatably mounted actuation element (2) with a locking track is rotatable for selection of a shift stage and at least one locking assembly (8, 9) with a rotatable locking member (13) may lock the actuation element (2) against rotation. The locking track is provided on the circumference of a ratchet wheel (4, 5) connected to the actuation element (2), and the locking assembly (8,9) includes a biasing member (12) applied to the locking member (13) to rotationally bias the locking member (13) such as to engage and lock the ratchet wheel. An electrically activated retaining device (11) is configured to retain the locking member (13) in a position such that the locking member (13) is prevented from rotating and engaging the ratchet wheel (4, 5) under the force of the biasing member (12).Type: ApplicationFiled: February 14, 2018Publication date: November 26, 2020Inventors: Ingemar Emricson, David Blank, Andreas Kammensjö

Patent number: 9638093Abstract: A process is provided for improving combustion control and fuel efficiency in rotary and reciprocating IC engines by enabling leaner combustion at higher compression ratios using less heat for ignition. Embodiments employ secondary chambers of minimal total volume within a cylinder periphery. These chambers communicate with a main chamber via conduits and enable a radical ignition (“RI”) species generation and supply process that starts in earlier cycles to be augmented and used in later cycles. Measures regulate the RI species generated and provided to the main chamber. These species alter dominant chain-initiation reactions of the combustion ignition mechanism. Also employed when preferable are fluids of higher heat of vaporization and volatility but lower ignitability than the fuel. This process improves combustion in radical ignition engines and radical augmented spark and compression ignition engines.Type: GrantFiled: April 17, 2015Date of Patent: May 2, 2017Assignee: HCRI Technologies International, LLCInventor: David A.

Publication number: 20150247445Abstract: A process for enhancement of combustion control in rotary and reciprocating IC engines for improving fuel efficiency by enabling leaner combustion at higher compression ratios. Embodiments supporting this process employ a fluid of higher heat of vaporization and higher volatility but lower ignitability than the fuel to increase the compression ratio required for self ignition. These have secondary chambers in a cylinder periphery for radical ignition (“RI”) species generation in an earlier cycle for use in a later cycle. These chambers communicate with a main chamber via conduits. Measures regulate the RI species generated and provided to the main chamber. These species then alter the dominant chain-initiation reactions of the main combustion ignition mechanism by lowering the heat and the fuel ratios required for combustion. This improves combustion in radical ignition engines and radical augmented spark and compression ignition engines.Type: ApplicationFiled: May 13, 2015Publication date: September 3, 2015Inventor: David A.

Patent number: 7832372Abstract: A process is provided for enhancing homogeneous combustion and improving ignition in rotary and reciprocating piston IC engines. Physical embodiments supporting this process have secondary chambers embedded in the cylinder periphery to initiate radical ignition (“RI”) species generation in an earlier cycle for use in the main chamber combustion of a later cycle. These communicate with the main chamber via small conduits. Coordinated with the progressions facilitated by these secondary chambers are novel control measures for regulating the quantities of RI species ultimately generated for and conveyed to the later cycle. The pre-determinable presence of RI species so supplied then alters or adds controlled variety to the dominant chain-initiation reactions of the main combustion ignition mechanism of the later cycle. This presence does so by lowering both the heat and the fuel ratios required for starting and sustaining combustion.Type: GrantFiled: February 23, 2009Date of Patent: November 16, 2010Assignee: HCRI Technologies International, LLCInventor: David A.
