This abstract first appeared for US patent application 18972251 titled 'Rocker Arm for Brake with Integrated Hydraulic Capsule
Original Abstract Submitted
A hydraulic capsule for use in a rocker arm comprises a housing having an upper chamber that receives fluid and a lower chamber in fluid communication with the upper chamber, a pin disposed in the upper chamber and configured to be hydraulicly controlled to extend and/or retract, a check valve assembly disposed in the lower chamber and configured to selectively enable fluid communication between the upper chamber and the lower chamber based on the position of the pin, a plunger disposed in the lower chamber and configured to be hydraulicly controlled to move between an extended position and a retracted position, and a first spring coupled to the plunger and configured to bias the plunger in the retracted position. Particularly, in the retracted position, the plunger does not engage a valve bridge. In the extended position, the plunger is able to engage the valve bridge.
