    摘要: For operating pumps above the respective system resistance for all volume flows, for a spring-loaded, directly acting overflow valve for limiting the pressure in a system in which a liquid is lifted by a positive-displacement pump and flows through the system with varying rates of flow, the valve chamber (1) and the valve body (22) with the valve head (14) placed therein are constituted in such a way that the valve head, after lifting off from the valve seat (3), has a second active diameter which is bigger than the first active diameter, whereby the valve head (11) simultaneously releases, with increasing stroke of the valve body (22), an enlarging flowing-through cross section, whereby the valve body (22) is constituted in one part as a valve piston (11) sliding in the valve chamber (1) with a third active diameter which is bigger than the second active diameter so that the liquid flowing through the valve chamber (1), the valve being opened, produces a pressure difference which acts onto the valve piston (11) against the action of the first spring (21).

    摘要: An improved air conditioning system that cools or heats air very rapidly after being started. The system includes a main heater and a cooler which also functions as an auxially heater. The cooler includes a variable displacement compressor for compressing refrigerant gas. The compressor has a crank chamber and a discharge chamber. A crank mechanism is accommodated in the crank chamber. Compressed refrigerant gas is supplied to an external refrigerant circuit via the discharge chamber. The discharge chamber is connected to the external refrigerant circuit by a passage. A throttle valve is located in the passage. The throttle valve closes the passage immediately after the compressor is started, which quickly increases the pressure of the discharge chamber. As a result, the displacement of the compressor is increased quickly, and rapid heating or cooling results.

    摘要: A control unit for controlling a pressure buildup by a pump unit in a fuel injection system. The control unit has a control valve and a valve actuation unit connected to the control valve. The control valve is embodied as an inlet valve that opens inward in the flow direction. The control unit has a valve body that is supported so that the valve body moves axially in a housing of the control unit and rests against a valve seat of the control valve from the inside when the control valve is closed. In order to give the through flow curve of the control valve as flat a course as possible with small strokes (Ssmall) of the control valve. The control unit includes a throttle device that throttles the flow through the control valve when the control valve is open by a small stroke (Ssmall).

    摘要: A hydraulic control arrangement which is provided for the demand-feed-regulated supply of pressure medium to preferably a plurality of hydraulic consumers by proportionally adjustable directional valves. There are hydraulic pumps by which pressure medium can be conveyed in a quantity corresponding to the demand into a common inflow line leading to the directional valves. A first demand-feed regulator is assigned to the first hydraulic pump and a second demand-feed regulator to the second hydraulic pump. The two demand-feed regulators are capable of being acted upon, with the effect of increasing the pressure medium quantity discharged into the inflow line by the corresponding hydraulic pump, by a spring and, on a first active surface, by the pressure in a load-signaling line and, with the effect of reducing the pressure medium quantity discharged into the inflow line by the corresponding hydraulic pump, on a second active surface, by a pump pressure. Moreover, a nonreturn valve opening toward the inflow line is arranged between the first hydraulic pump and said inflow line. Either both hydraulic pumps or only the second hydraulic pump conveys pressure medium to the inflow line. In order to be more flexible here, a nonreturn valve opening toward the inflow line is also arranged between the second hydraulic pump and the latter. There are also members by which action of force on the demand-feed regulators can be changed that the hydraulic consumers can be supplied with pressure medium both solely by the first hydraulic pump and solely by the second hydraulic pump.
