Abstract: A brake transmission shift interlock actuator includes a bobbin that has an open end and a closed end. A plunger is slidably disposed within the bobbin and a plunger rod extends from the plunger. Moreover, a primary plate is installed within the open end of the bobbin. The plunger is movable between an unlocked position, wherein the plunger rod does not extend through the primary plate and a locked position, wherein a first end of the plunger rod extends through a bore formed by the primary plate. Further, a magnetic force of attraction between the plunger and the primary plate diminishes as the plunger approaches the primary plate.

Abstract: A tubeless actuator includes a frame in which a primary plate and a secondary plate are disposed. A bobbin is disposed within the frame between the primary plate and the secondary plate. The bobbin is keyed to the secondary plate in order to maintain the alignment between the bobbin and the secondary plate. Moreover, the plunger slides in direct contact with the bobbin.

Abstract: A pneumatic module includes an actuator assembly and a manifold. The actuator assembly includes a main body having a bore, an armature, overmolded primary and secondary plates, a coil and a frame. The manifold includes a valve seat, a control port and a supply port. When the actuator is in a de-energized state, the armature is forced against the valve seat by a spring, sealing off the supply port from the control port. When the actuator is in an energized state, current flows through the coil, thereby generating a magnetic field. The magnetic field forces the armature to move toward the primary plate, causing the valve seat becomes unsealed. Once the valve seat is unsealed, fluid flow is permitted between the supply port and the control port. The one end of the armature has an endcap to minimize mechanical noise generated by movement of the armature against the spring. The frame surrounding the actuator assembly has flanges extending from both ends.

Abstract: A 3/2 normally closed module includes a main body, a housing and a magnetically energizable coil. The main body includes a bore, an armature and a rod. The housing includes first and second valve seats and is configured to receive a first and second ball. The housing also includes a first, a second and a third port. When the module is in an energized state, current flows through the coil, generating a magnetic field. The magnetic field forces the armature against the rod, which in turn, forces the first ball to engage the first valve seat. As the first ball engages the first valve seat, the first ball forces the second ball to disengage from the second valve seat. As a result, a fluid flow path is created between the first and second ports. When the module is in a de-energized state, a spring, disposed between the main body and the second ball, forces the second ball to engage with the second valve seat.

Abstract: An actuator assembly operates a device in a normally open mode and a normally closed mode. The actuator assembly includes a bobbin around which a coil is wound. The coil receives an electrical current to induce a magnetic field thereabout. A rod extends along the longitudinal axis. The rod is movable along the longitudinal axis in response to the magnetic field. The actuator assembly also includes a plunger extending through a portion of the bobbin. The plunger is movable with respect thereto in response to changes in the magnetic field. The plunger includes a rod receptacle for fixedly securing the rod therein allowing the rod to move with the plunger. The plunger also includes an opposing rod receptacle allowing the rod to be received thereby when the actuator assembly is in the normally closed orientation.
