An integrated driveline (136, 236, 336, 36, 436) slip clutch (154, 254, 354, 454) system for a large square baler (28) for controlling a transfer of power from a tractor (26) to the baler (28). The clutch (254) system includes a slip clutch (154, 254, 354, 454) having a number of clutch plates (388). The slip clutch (154, 254, 354, 454) is moveable between a disengaged relationship in which no power is transferred from a driveline (136, 236, 336, 36, 436) to a gearbox (140, 240, 340, 40, 440), and one or more engaged relationships in which amounts of power are transferred from the driveline (136, 236, 336, 36, 436) to the gearbox (140, 240, 340, 40, 440). Movement of the slip clutch (154, 254, 354, 454) between engagement relationships may be controlled mechanically (by, e.g., centrifugal force) or electronically. For electronic control, a controller receives input data from sensors (504) concerning operation of the baler (28), and controls a valve to introduce or remove hydraulic fluid to or from a clutch cylinder (276, 376, 476) or a double acting cylinder (496) in accordance with a pressure control profile which ramps hydraulic pressure through levels to achieve the engagement relationships.

A method for adjusting an operating point of a hydraulic actuator arrangement, in which a volumetric flow source is connected to a hydraulic cylinder via a pressure line which is filled with a hydraulic fluid, wherein a volume of the hydraulic fluid is regulated via the volumetric flow source and the operating point corresponds to a position of the actuator arrangement for a predefined parameter of a device which is to be actuated by the actuator arrangement, wherein the volume of the hydraulic fluid which is required to adjust the operating point is derived from a rotational position of a volumetric flow source motor and/or the volumetric flow source. In a method which facilitates a reliable start of the volume determination, a volume determination is started by means of a rotary angle regulation at a predefined pressure, wherein the predefined pressure is lower than a system pressure.

A hydraulic tube connector for vehicle may include a connector body including a through hole into which a tube having a tube protrusion protruding outward is inserted, and a pair of guide grooves formed around the through hole and a coupling member configured to couple the tube with the through hole of the connector body, wherein the coupling member includes a tube coupling portion configured to surround the tube and a pair of coupling guides configured to be inserted into the pair of guide grooves.

A method for adjusting and adapting an operating point of a hydraulic actuator arrangement, in which a volume flow source is connected to a hydraulic cylinder via a pressure line that is filled with a hydraulic fluid. The method includes regulating a volume of the hydraulic fluid by the volume flow source, wherein an operating point of a position of the actuator arrangement corresponds, with respect to a predefined parameter, to a device which is to be actuated by the actuator arrangement. A modified volume of the hydraulic fluid which is necessary to adjust the operating point is derived from a rotational position of a volume flow source motor and/or of the volume flow source.

Pressure in subsea systems, and accumulators of the subsea systems, may be increased through the use of a supercharge cylinder to generate higher pressures from an initial pressure provided from a surface vessel. The supercharge cylinder may include a piston that can be stroked to increase pressure stored in accumulators located near subsea systems, such as a blowout preventer (BOP). The increased pressure provided by the supercharge cylinder may allow the same number of accumulators to be used in the subsea system but allow additional effective hydraulic fluid to be stored in the accumulators.
