Provided herein is an improved a bi-stable actuator including a first core component coupleable to a housing, the first core component including a central bore containing a shaft and a shaft spring. The actuator may further include a second core component extending around the first core component, wherein the second core component and the first core component are axially moveable relative to one another, and a third core component extending within the second core component, wherein the third core component and the second core component are axially moveable relative to one another. The actuator may further include a positioning sphere extending through an opening of the first core component, wherein the positioning sphere abuts the second core component when the bi-stable actuator is in a first position, and wherein the positioning sphere abuts a detent of the shaft when the bi-stable actuator is in a second position.

An actuator assembly including a first actuator having a first magnetically actuated plunger and a first latching plate, where the first plunger is operable to be magnetically latched to the first latching plate. The actuator assembly further includes a second actuator coupled to and axially aligned with the first actuator. The second actuator includes a second magnetically actuated plunger, a second latching plate, a sleeve positioned within and extending from the second plunger and being rigidly secured to the first plunger, and a tolerance spring wrapped around the sleeve. The second plunger is operable to be magnetically latched to the second latching plate, where latching of the second plunger causes the tolerance spring to compress and provide additional latching force of the first plunger to the first latching plate.

Contactor for an electric vehicle, with at least one fixed contact element and a movable contact element which, in a disconnection position, is spaced from the at least one fixed contact element in order to interrupt an electrical connection of the two contact elements, and which, in a closed position, is in electrically conductive contact with the at least one fixed contact element in order to create an electrical connection of the two contact elements, and with a switch actuator, associated with the movable contact element, which is designed to move the movable contact element into the disconnection position or into the closed position.

An actuator, a remote triggering apparatus, a governor, and an elevator. The actuator includes: a mandrel, the mandrel having a proximal end and a distal end, and the mandrel being driven to move from a contraction position toward an actuation position; a mandrel sleeve; and a shell, the shell defining a channel, wherein the actuator further includes at least one sliding member, and when the mandrel moves from the contraction position toward the actuation position, the at least one sliding member is located at a first radial position where the mandrel is joined to the mandrel sleeve, such that the mandrel sleeve can move along the channel together with the mandrel; and wherein at the actuation position, the at least one sliding member moves outward radially to a second radial position where the mandrel sleeve is joined to the shell, thus locking the mandrel sleeve.

A solenoid for a solenoid-actuated valve includes a coil, a flux tube, a pole piece disposed axially from the flux tube and encircled by the coil, a movable armature disposed in the flux tube and the pole piece, and a latch disposed between the flux tube and the pole piece to selectively latch the armature into at least one position.

A latch device (12) for a hydraulic valve (10) is proposed. The latch device (12) comprises a housing (22) and a latch shaft (26), which is supported such that it can move in the housing (22). In order to create a latch device (12), independent of the hydraulic provisioning, the provision of at least one magnetizable ring beam arrangement (38), which is supported on the latch shaft (26), and an electric solenoid arrangement (40), located on the housing (22) around the ring beam arrangement (38) is also proposed, wherein by the supply of current to the solenoid arrangement (40), a positioning force can be produced on the ring beam arrangement (38). Furthermore, a hydraulic valve (10) with the corresponding latch device (12) and a hydraulic arrangement (92) for such a valve (10) are also proposed.

A solenoid valve comprising a valve portion and a solenoid portion. The valve portion has a pin, the pin having a groove. The solenoid portion has an aperture configured to receive the pin. A resilient locking device is located in the aperture, the resilient locking device configured to engage the groove when the pin has been inserted into the aperture to releasably hold the pin in the aperture. There is also a movable cap having a first and second position wherein, in the first position the movable cap does not abut the resilient locking device and wherein, in the second position, the movable cap abuts the resilient locking device so as to prevent movement of the resilient locking device out of the groove. A method of locking a valve portion to a solenoid portion of a solenoid valve is also disclosed.
