Latch device

A system comprising:

• a hydraulic valve including:
• a latch shaft movable within a housing of the hydraulic valve;
• a magnetizable ring beam arrangement that is coupled to the latch shaft between a first housing wall and a second housing wall, the magnetizable ring beam arrangement comprising a first ferromagnetic-adjusting ring, a second ferromagnetic-adjusting ring, and a tension element positioned between the first ferromagnetic-adjusting ring and the second ferromagnetic-adjusting ring;
• and
• an electrical solenoid arrangement positioned within the housing and coaxially around the magnetizable ring beam arrangement, wherein the electrical solenoid arrangement is configured to:
• (i) receive a first electrical signal and responsively generate a first positioning force on the magnetizable ring beam arrangement configured to cause the magnetizable ring beam arrangement to move, in a first direction, into a first deflection position at which the magnetizable ring beam arrangement contacts the first housing wall and the tension element is uncompressed, (ii) receive a second electrical signal and responsively generate a second positioning force on the magnetizable ring beam arrangement configured to cause the magnetizable ring beam arrangement to move, in a second direction, into a second deflection position at which the magnetizable ring beam arrangement contacts the second housing wall and the tension element is uncompressed, the second direction being opposite to the first direction, and (iii) receive a third electrical signal and responsively generate a third positioning force on the magnetizable ring beam arrangement configured to cause the magnetizable ring beam arrangement to move in the first direction past the first deflection position and into a third deflection position at which the magnetizable ring beam arrangement contacts the first housing wall and the tension element is compressed;
• an input device configured to transmit input signals;
• and
• a control unit coupled to the hydraulic valve and the input device, the control unit configured to receive the input signals from the input device and operate the hydraulic valve based on the input signals, wherein the control unit is configured to cause the hydraulic valve to enter (i) the first deflection position in response to a first input signal from the input device,
• (ii) the second deflection position in response to a second input signal from the input device,
• and (iii) the third deflection position in response to a third input signal from the input device.
