摘要： The invention relates to a device (10) for pressure regulation, having a housing (11) and a closing body (12) received axially movably therein, wherein the housing (11) has at least one pressure medium inlet (21) and one pressure medium outlet (22), and the closing body (12) is prestressed by a helical spring (14) against a valve seat (11′) in the housing, and at least one compensation means for the helical spring (14) is provided. The invention provides that as the compensation means, a compensation element (15) disposed between the closing body (12) and an end, oriented toward the closing body (12), of the helical spring (14) is provided, which is braced resiliently in the radial direction on the inner wall of the housing (11) and, with its central region (15′), is in preferably frictional-engagement contact with the closing body (12). The central region (15′) of the compensation element (15) is embodied as dome-shaped, and radially protruding spring arms (15″) are disposed peripherally to the central region (15′) of the compensation element (15).

摘要： The pressure regulating valve (2) proposed here can be designed with the aid of the outflow throttle restriction (28) downstream of the valve seat (22) in such a way that the pressure regulating valve (2), as the fluid flow becomes greater, sets or adjusts a smaller pressure difference at the pressure regulating valve (2), as a result of which the line losses that can never be avoided can be compensated for. The pressure regulating valve is suitable in particular for a fuel supply system of a motor vehicle having an internal combustion engine.

摘要： The unit includes an electric drive motor (12) and a pump section (24) that are situated next to each other in a common housing (10) designed at least nearly in the shape of a hollow cylinder. The pump section (24) comprises a delivery element (26) rotating in a pump chamber (30), and one wall (32, 34) each forms a boundary of the pump chamber (30) with the drive motor (12) and with the outside of the housing (10) in the direction of the axis of rotation (28) of the delivery element (26). The walls (34) forming the boundary of the pump chamber (30) with the outside of the housing (10) is formed as a single component with the housing (10), and the walls (32) forming the boundary of the pump chamber (30) with the drive motor (12) is inserted into the housing (10) as a separate component. Due to the fact that the wall (34) forming the boundary of the pump chamber (30) with the outside is integrated with the housing (10), no separate steps are required to manufacture and assemble said wall and housing, and the pump chamber (30) is sealed off completely from the outside of the housing (10), because no joints are present that would have to be sealed off.

摘要： A liquid filter (1) with a built-in pressure regulator (11) for fuel is proposed, in which the pressure regulator (11) with its diaphragm (32) is mounted on the inside of a cap (14) that has the inflow connector (16) and the tank connector (17). The diaphragm (32), which experiences a flow on its inside, is acted upon by the pressure of the fuel on the clean side (25) of the filter element (21), and the flow through the filter element is radially from the outside inward. Integrating the pressure regulator (11) in the cap enables a simple, compact, economical design of the liquid filter (10), through whose valve (36) in the pressure regulator (11) only cleaned fuel flows.

摘要： A pressure control valve in which the mass to be moved by the diaphragm is reduced by providing that a valve seat body having a valve seat face is placed in a middle region of the diaphragm. When the valve seat face lifts away from the valve closing body, fuel to be diverted flows from the pressure control side of the diaphragm to the return side of the diaphragm, via the valve seat face and a return conduit The pressure control valve is especially suitable for use in fuel supply systems of internal combustion engines.

摘要： The pressure regulator is suitable for disposition in a fuel pump. The pressure regulator has a metal bellows, which is connected on one end to a retaining ring and on the other end to a disk. An element is screwed into the retaining ring, which element carries a valve closing member of a seat valve, whose valve seat encompasses an outlet bore of the disk. The interior of the bellows communicates with the compression side of the fuel pump by means of an opening of the element, and with the intake side by means of the outlet bore of the disk.
