Patent number: 11268410Abstract: An actuation apparatus for actuating a component of a switchable valve train device of an internal combustion engine includes: a support body for mounting on a cylinder head cover of the internal combustion engine; an actuation lever mounted to the support body for pivotal movement of the actuation lever between a first position for actuation of the component and a second position for allowing de-actuation of the component; and a biasing means for urging the actuation lever from the second position towards the first position. In use, the biasing means becomes biased when an actuation source causes the actuation lever to pivot to the second position. When the actuation source attempts to actuate the component when the component is non-actuatable, the biasing means causes the actuation lever to pivot from the second position to the first position, thereby to actuate the component when the component becomes actuatable again.Type: GrantFiled: March 6, 2019Date of Patent: March 8, 2022Assignee: Eaton Intelligent Power LimitedInventors: Yuriy Mysak, Nicola Andrisani, Emanuele Raimondi

Patent number: 10968790Abstract: An actuation apparatus actuates a latching arrangement of a switchable valve train component of an internal combustion engine. The apparatus includes: a lever configured to contract an actuation source and configured to contact the latching arrangement; and a bias. The bias contacts the lever. The bias is configured such that, in use, the bias becomes biased by the lever when the actuation source moves the lever when the actuation source attempts to actuate the latching arrangement, via the lever, when the latching arrangement is non-actuatable, whereby the bias causes the lever to actuate the latching arrangement when the latching arrangement is actuatable again.Type: GrantFiled: August 6, 2018Date of Patent: April 6, 2021Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Emanuele Raimondi, Nicola Andrisani

Patent number: 10961876Abstract: A rocker arm for a valve train assembly includes: a first body; a second body mounted for pivotal movement with respect to the first body; and a latching arrangement. The latching arrangement includes a latch pin drivable in response to an external actuator from a first position in which the first body and the second body are un-latched to a second position in which the latch pin latches the first body and the second body together. The latching arrangement includes a piston member and a first biasing member. The piston member is arranged such that if the external actuator attempts to cause the latch pin to be driven from the first position to the second position at a time when the latch pin is prevented from being driven, the piston member moves to bias the biasing member so that the biasing member urges the latch pin to the second position.Type: GrantFiled: April 21, 2017Date of Patent: March 30, 2021Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Nicola Andrisani, Emanuele Raimondi, Alessio Lorenzon

Publication number: 20200308993Abstract: A rocker arm for a valve train assembly includes: a first body; a second body mounted for pivotal movement with respect to the first body; and a latching arrangement. The latching arrangement includes a latch pin drivable in response to an external actuator from a first position in which the first body and the second body are un-latched to a second position in which the latch pin latches the first body and the second body together. The latching arrangement includes a piston member and a first biasing member. The piston member is arranged such that if the external actuator attempts to cause the latch pin to be driven from the first position to the second position at a time when the latch pin is prevented from being driven, the piston member moves to bias the biasing member so that the biasing member urges the latch pin to the second position.Type: ApplicationFiled: April 21, 2017Publication date: October 1, 2020Inventors: Nicola ANDRISANI, Emanuele RAIMONDI, Alessio LORENZON

Patent number: 10781725Abstract: A valve train assembly includes: at least one dual body rocker arm having a first body, a second body, a latching arrangement for latching and unlatching the first body and the second body, the latching arrangement having a latching pin that is biased to an unlatched configuration; and an actuator arrangement for controlling the latching arrangement, the actuator arrangement being able to contact the latching arrangement to cause the latching pin to be moved into a latched configuration in which it latches the first and second bodies together. In use, movement of the rocker arm under action of a cam to cause a valve event moves the actuator arrangement out of contact with the latching arrangement while a contact force between the latching pin and one or other of the first and second bodies maintains the latching pin in the latched configuration.Type: GrantFiled: October 24, 2017Date of Patent: September 22, 2020Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Emanuele Raimondi, Nicola Andrisani, Alessio Lorenzon

Publication number: 20200271023Abstract: An actuation apparatus (3) for actuating a latching arrangement (40) of a switchable valve train component (2) of an internal combustion engine is disclosed. The actuation apparatus comprises a lever (33) for contacting an actuation source (100) and for contacting the latching arrangement (40), and a biasing means (31). The biasing means (31) contacts the lever (33). In use, the biasing means (31) becomes biased by the lever (33) when the actuation source moves the lever (33) when the actuation source (100) attempts to actuate the latching arrangement (40), via the lever (33), when the latching arrangement (40) is non-actuatable. The biasing means (31) causes the lever (33) to actuate the latching arrangement (40) when the latching arrangement (40) is actuatable again. Also disclosed is a valve-train assembly.Type: ApplicationFiled: August 6, 2018Publication date: August 27, 2020Inventors: Emanuele Raimondi, Nicola Andrisani
