摘要： A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

摘要： When temperature is low, a low-temperature mode is selected, followed by the activation of the heating mode functionality 25a of a PCU 25. Specifically, the PCU 25 sets the ratio of energy recovered by a capacitor 23 to be equal to or greater than the largest value of the energy recovery ratios of the capacitor 23 in a normal mode (e.g., assist motor 22 : capacitor 23 = 2 : 8). Thus, more energy is stored on the capacitor 23 than in the normal mode, helping the capacitor 23 generates heat. As a result, the liquid temperature of the coolant is increased, and its viscosity is reduced accordingly. As above, the invention provides a simple cooling system to be mounted on a hybrid working machine, which is capable of preventing decreases in energy efficiency at low temperature.

摘要： Disclosed is a device for controlling the operation of a ventilator, which can be driven by a hydraulic motor (1), of a cooling device, in particular in a working appliance for agricultural use, wherein the hydraulic motor (1) can be supplied with pressure fluid by means of a hydraulic pump (3) via a valve arrangement (7) than can be set to a first valve position for operation of the hydraulic motor (1) in a first direction of rotation and to a second valve position for operation of the hydraulic motor (1) in a second direction of rotation, a control device (21) being present, by means of which the valve arrangement (7) can be set to an intermediate position which reduces the pressure supply to the hydraulic motor (1) during transitions between the first and second valve positions for a time period that allows the ventilator speed to be reduced.

摘要： A cooling fan control unit, in response to an operation performed at the rotation direction selector switch to select a reverse rotation setting while the cooling fan is rotating forward, lowers a relief pressure setting at the variable relief valve to a predetermined lower limit value over a predetermined length of time, and once the discharge pressure at the hydraulic pump detected by the pressure sensor is lowered to a predetermined switch-over pressure, executes control so as to switch the direction of flow of pressure oil to the hydraulic motor to the reverse direction by switching the direction switching valve and raises the relief pressure setting at the variable relief valve to a reverse rotation pressure setting, at which the hydraulic motor rotates in the reverse direction, over a predetermined length of time.

摘要： A hydraulic system for a power-take-off in a utility vehicle is described, having a pump (8) supplying hydraulic fluid to the clutch (1), the brake (2) and a lubricating circuit, a control valve for engaging and releasing the clutch and a device containing a pressure-limiting valve (12) which makes a high system pressure available when the clutch is engaged and a lower system pressure when the clutch is released.
In order to keep loss of power in the pump as low as possible and reduce the number of components required in a hydraulic system of this type, the system pressures are controlled by the pressure applied to the engaged clutch. Consequently, the system pressures can be adjusted regardless of the design of control valve used. This means that less expensive 3/2-way valves or 3/2-control valves can be used. This also has an advantage in that different system pressures can be produced using a single pressure-limiting valve. The hydraulic system is suitable for all types of utility vehicle with a power-take-off.
