A simple, compact, and economical motor/pump unit for supplying vacuum to a pneumatic brake booster of a motor-vehicle brake system, wherein the motor/pump unit is designed as a diaphragm pump having a single elastomeric diaphragm, which is moved by an electrically operated motor unit by an eccentric drive, and has a pump housing and a working-space cover and the diaphragm is clamped between the pump housing and the working-space cover at the radial outer edge of the diaphragm in a sealing manner and the working-space cover is designed as a multi-part working-space cover having an upper cover, a lower cover, and an inlet valve and an outlet valve, which are arranged between the upper cover and the lower cover and control the air circulation through the working space.

Motor/pump unit having a single elastic diaphragm

In an electric motor-pump assembly, two working diaphragms, each delimiting a working chamber, are cyclically driven by a crank drive via connecting rods. The crank drive includes eccentrics for each connecting rod, which are placed on an axial bearing journal in the extension of an output shaft of an electric motor. In order to ensure a rotationally fixed connection between the eccentrics and the bearing journal to be produced and in order to ensure an angularly precise position of the two eccentrics, each of the eccentrics is connected to the bearing journal by a positively locking engagement.

Electric motor-pump assembly

The invention relates to a pump unit that can be driven by an electric motor, in particular for providing vacuum for a pneumatic brake booster, including a pump housing that can be closed by a working-chamber cover and at least one elastic displacement element, wherein a working chamber is bounded between the displacement element and the working-chamber cover and wherein inlet valves and outlet valves and inlet channels and outlet channels associated with the valves are associated with the working chamber. According to the invention, in order to reduce noise emissions, devices for reducing a contact surface between the working-chamber cover and the pump housing are provided.

Pump unit driven by an electric motor

A pump assembly for supplying negative pressure to a pneumatic brake booster, wherein the pump assembly has at least two elastic displacement elements which are moved by connecting rods, the connecting rods each being rotatably mounted on an eccentric element. The eccentric element has a bearing seat element and a force element. At least two eccentric elements are secured next to each other on a drive shaft that rotates about an axis of rotation and an interlocking anti-rotation device is provided that determines a defined angular position of the eccentric elements relative to each other about the axis of rotation. In order to improve the ease of assembly and simplify the manufacturability, the anti-rotation device is designed as shaped elements of the bearing seat element in such a way that they engage in each other in an interlocking manner when the eccentric elements are in a defined angular position relative to each other.

Pump assembly

A motor-pump unit, for providing pressure for a brake actuating device having a pneumatic brake booster including a pump and an electric motor driving the pump, the pump being a dual diaphragm pump having two opposed working diaphragms, each of which is clamped between a pump casing and a working chamber cover and delimits a working chamber, and moveable by a crank drive having connecting rods and bearings, the working diaphragm connected firmly to a tappet and, together with the connecting rod, in each case forming a diaphragm unit. In order to provide a low-noise motor-pump unit which is more cost-effective and requires reduced expenditure on assembly, the connecting rods are made of plastic, wherein in each case one tappet and one bearing are encapsulated with the material of the connecting rod. Alternatively, the connecting rods can be formed in one piece with the tappet and provided as sintered components.

Motor pump unit

Disclosed is a motor-pump assembly () for a brake actuating device of a motor vehicle brake system with a pneumatic brake booster. An electric motor () drives a double diaphragm pump () with two working diaphragms () which are located opposite one another. Air expelled from the working spaces () is directed into an interior space () surrounding a crank drive () of the pump housing (). An air outlet unit () permits low-noise expulsion of the air from the interior spaceby deflecting the air. In order to make available a low-noise, cost-reduced motor-pump assembly the eccentrics () each have an unbalance weight () integrally molded onto the eccentric ().
