The invention relates to a vehicle seat for a vehicle, comprising a seat part that has a seat part frame, and comprising a backrest part, the seat part and/or the backrest part being designed so as to be adjustable with respect to a degree of inclination, and comprising at least one switching console element which comprises at least one control element for actuating at least one function of at least one actuator element of the vehicle, the switching console element being mounted on the seat part frame to the side of the seat part, a first portion of the switching console element being designed so as to be displaceable at least in the longitudinal direction of the vehicle seat.

Assemblies to cut a hollow piling are provided, which may have a pressurized hydraulic fluid supply configured to supply enough force to cut through up to the circumference of a piling having a housing having a cavity to receive the hydraulic fluid, the housing having at least one cylinder wall; at least one piston assembly slidably disposed within the at least one cylinder wall configured to extend from the at least one cylinder wall in response to the introduction of pressurized hydraulic fluid into the housing cavity; and a blade attached at a radially distal end of the piston assembly, whereby as the blade extends through the cylinder wall, a cutting force is applied to an encountered piling wall.

A working machine includes a hydraulic pump, a first traveling device to be driven by a first traveling hydraulic actuator, a second traveling device to be driven by a second traveling hydraulic actuator, a first output tube to connect a first output port of the hydraulic pump to the first traveling hydraulic actuator, a second output tube to connect a second output port of the hydraulic pump to the second traveling hydraulic actuator, a first operation device to operate the first traveling device, a second operation device to operate the second traveling device and a correction mechanism to equalize a driving force of the first traveling hydraulic actuator and another driving force of the second traveling hydraulic actuator when the first operation device and the second operation device are operated each at same operation extents to perform a straight-traveling operation.

A telescopic actuator comprising a cylinder (2) in which a rod (3) is mounted to slide along a sliding axis (X), the actuator including a locking member comprising a locking finger (10) that is movable along a locking direction (Y) that is perpendicular to the sliding axis, between a locking position in which an end (9) of the locking finger (10) is engaged in a groove (8) of the rod in order to lock the rod in position, and a retracted position in which the end of the finger is disengaged from the groove in order to release the rod, a locking indicator (20) being secured to the locking finger to be movable between a position indicating locking when the locking finger is in the locking position, and a position indicating unlocking when the locking finger is in the retracted position, the actuator being characterized in that the locking indicator is secured to the locking finger by a connection (22, 23, 24) suitable for being interrupted in the event of the end of the finger being broken off while the rod is locked, a thrust spring (25) being arranged in the locking finger to push the locking indicator towards the position indicating unlocking when said connection is interrupted.

A control system and method for controlling the positioning of an adjustable deflector plate employed in a harvesting combine to adjust a side-to-side flow of crop residue to spreaders associated with the combine and the distribution thereby. The deflector plate is operably extendable into the flow of crop residue to redirect crop residue impinging the deflector plate. The deflector plate is adjusted based upon a comparison between the open/closed states of valves associated with the control system.

Systems and methods for protecting a turbomachine may include a trip throttle valve having a throttle valve assembly and a trip valve assembly. The trip valve assembly may include a plurality of trip valves fluidly coupled to a hydraulic cylinder of the throttle valve assembly via a first flow path and a second flow path in parallel with one another. The trip valve assembly may also include a plurality of isolation valves fluidly coupled to the hydraulic cylinder via the first flow path and the second flow path. The plurality of isolation valves may be configured to selectively prevent fluid communication between the plurality of trip valves and the hydraulic cylinder to allow testing of one or more of the plurality of trip valves during operation of the turbomachine.

A hydraulic drive including at least one hydraulic cylinder that includes a piston chamber, an annulus, and a piston that separates the piston chamber from the annulus. The hydraulic drive also includes a first hydraulic pump hydraulically connected with the piston chamber, a second hydraulic pump hydraulically connected with the annulus, a third hydraulic pump, and a directional control valve that has a first switching position and a second switching position. The third hydraulic pump in the first switching position of the directional control valve is hydraulically connected with the piston chamber, and the third hydraulic pump in the second switching position of the directional control valve is not hydraulically connected with the piston chamber.

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

A hydraulic device of the present invention includes an outer tube, a bottom portion that closes one end of the outer tube, an inner tube inserted into the outer tube, a movable portion movable relatively to the outer tube and the inner tube in an axial direction, coupling members attached to the outer periphery of the inner tube, and fixing tools that are in contact with the coupling members and fix the inner tube to the bottom portion.
