Abstract
In one embodiment, a lifter assembly comprises a lifter having a latching mechanism, a slot arranged on an outer wall of the lifter and comprising an inlet that provides access to the latching mechanism, and a pin comprising a fluid channel. The latching mechanism is switchable between a latched position and an unlatched position. The pin is configured to interface with the slot such that the lifter is prevented from rotation about a lifter axis. The fluid channel is configured to be fluidly coupled to the inlet of the slot.
Claims29
A lifter assembly, comprising:
- a lifter comprising a latching mechanism configured to switch between a latched position and an unlatched position,
- a slot arranged on an outer wall of the lifter, the slot comprising an inlet communicating with the latching mechanism, and
- a pin operatively coupled to a structure outside the lifter assembly and configured to interface with the slot such that the lifter assembly is prevented from rotating about a lifter axis, the pin comprising a fluid channel configured to be fluidly coupled to the inlet of the slot.
An engine block assembly, comprising:
- an engine block;
- and
- a lifter assembly housed inside the engine block, the lifter assembly comprising:
- a lifter comprising a latching mechanism configured to switch between a latched position and an unlatched position,
- a slot arranged on an outer wall of the lifter, the slot comprising an inlet communicating with the latching mechanism, and
- a pin configured to interface with the slot such that the lifter is prevented from rotating about a lifter axis, the pin comprising a fluid channel configured to be fluidly coupled to the inlet of the slot;
- wherein the pin is mounted through an outer wall of the engine block so as to interface with the slot.
A lifter assembly, comprising:
- a lifter comprising a latching mechanism configured to switch between a latched position and an unlatched position,
- a slot arranged on an outer wall of the lifter, the slot comprising an inlet communicating with the latching mechanism, and
- a pin configured to interface with the slot such that the lifter assembly is prevented from rotating about a lifter axis, the pin comprising a fluid channel configured to be fluidly coupled to the inlet of the slot so as to convey a fluid pressure which actuates the latching mechanism between the latched position and the unlatched position.
