Abstract: An arrangement for throttling a fluid flow includes a throttle element arranged so as to influence a flow cross section in a fluid duct. The throttle element has a resiliently elastic disc-shaped basic body which is arranged with a top side and a bottom side between at least two supports in the fluid duct. The body is arranged in such a way that the flow cross section can be variably adjusted as a function of a pressure difference between the top side and the bottom side of the resiliently elastic disc-shaped basic body. At least one support bears against the top side of the resiliently elastic disc-shaped basic body, and at least one support bears against the bottom side of the resiliently elastic disc-shaped basic body.

Abstract: A pump, in particular for a vehicle brake system, includes a pump piston which is guided displaceably in a pump cylinder. The pump cylinder is produced by deep drawing.

Abstract: A device for throttling a fluid flow includes a basic body which has at least one throttle point with a predefinable opening cross section. The basic body has a resilient configuration at least in a region of the at least one throttle point. Accordingly, the opening cross section of the at least one throttle point is configured to be set in a variable manner as a function of a pressure difference.

Abstract: A non-return valve for a fluid pump, in particular of a safety brake system of a motor vehicle, includes a through-flow opening configured to be closed by a valve element. The valve element is configured to be displaced against the spring force of a valve spring made of coiled round wire to expose the through-flow opening. The round wire is coiled in one plane and is arranged with respect to the valve element such that the plane extends at least substantially perpendicularly to the displacement direction of the valve element.

Abstract: In a valve, in particular of a hydraulic pixton pump, includes a valve seat, a valve closing element, and a positioning mechanism. A valve opening is formed in the valve seat. The valve seat also has a front side and a rear side. The valve closing element is arranged on the front side of the valve seat in order to open and close the valve opening as desired. The positioning mechanism is configured to hold the valve closing elementrelative to the valve seat. The positioning mechanism is arranged on the rear side of the valve seat and is connected to the valve closing element through the valve opening.

Abstract: An annular seal element is configured to seal off a pressurized region filled with a fluid. The annular seal element has one end face which is pressed onto a contact surface of a piston. The end face is formed with a sealing contour in such a way that the sealing contour is elastically deformable on the contact surface by the pressure exerted.

Abstract: A piston pump, in particular a hydraulic piston pump, includes a piston movable in a piston housing and a piston guide element, arranged between the piston housing and the piston, for guiding and/or mounting the piston. The piston guide element is configured as a coating applied fixedly at least to an inner surface area of the piston housing or to an outer surface area of the piston.
