A hydraulic component includes a piston and a cylinder with a piston receiving space in which the piston is displaceably arranged while defining a chamber, via which a pressure may be applied to a first end face of the piston, from a control chamber, via which pressure may be applied to a second end face of the piston which faces away from the first end face. A first hydraulic line and a second hydraulic line open into the chamber and a control line, which branches off from the first hydraulic line, opens into the control chamber. Due to the respective pressure ratio between the pressure in the chamber and the control chamber, the piston is displaceable from a closed position, in which the first and second hydraulic lines are fluidly decoupled, into an open position, in which the first and second hydraulic lines are fluidly connected, and vice versa.

A hydraulic circuit for controlling the application of pressurized cooling fluid to the clutches of a dual clutch transmission including a cooling unit in fluid communication with a source of the pressurized cooling fluid and adapted to exchange heat from the cooling fluid with another media. The circuit also includes at least one regulator in fluid communication with the source of the pressurized cooling fluid and separately in fluid communication with the cooling unit, and with the clutches. The regulator is adapted to operatively provide the cooling fluid to the clutches. The circuit further includes at least one control actuator adapted to selectively control the regulator to provide a first variable predetermined amount of cooling fluid from the cooling unit to the clutches as primary cooling, and to provide a second variable predetermined amount of cooling fluid from the source to the clutches thereby supplementing the cooling fluid from the cooling unit.

A drawing device for a press is provided with a drawing slide, with a sheet holder having a sheet held therein, and with a pressure cheek which is arranged under the sheet holder and is connected with a piston rod which can be displaced in parallel to the drawing direction. The piston rod is operatively connected with a preacceleration piston of a preacceleration cylinder. The drawing cylinders are applied to the pressure cheek by way of drawing rods, in which case the drawing cylinders have drawing pistons with first and second piston spaces. The first piston space directed to the drawing rod is pressure controlled during the drawing operation for the sheet forming. In the event of a press stoppage during a sheet forming, a control valve device can be activated so that, for maintaining the pressure existing in the first piston space at the start of the press stoppage during the time of the press stoppage, pressure medium can be charged into the first piston space by way of a pressure medium generator.
