Patent application number | Description | Published |
20100294126 | HYDRAULIC FLUID PUMP HAVING A SEALING ELEMENT - In a hydraulic fluid pump, in particular for a vehicle brake system, having a housing and a piston that is mounted in an axially movable manner in the housing in a piston chamber. A drive moves the piston and a sealing element seals off the piston chamber in the direction of the drive. The sealing element is designed as a diaphragm that extends through the piston chamber transversely with respect to the movement direction of the piston. | 11-25-2010 |
20120141304 | Pump Housing for a Hydraulic Unit in a Motor Vehicle - A pump housing for a hydraulic unit in a motor vehicle, includes a body that is provided with openings for accommodating components of an associated pump. One of the external surfaces of the body is designed such that a motor can be mounted thereon. A cutting process is not used to machine the external surface for mounting the motor. | 06-07-2012 |
20130224046 | DEVICE FOR THROTTLING A FLUID FLOW, AND CORRESPONDING PISTON PUMP FOR DELIVERING FLUIDS - 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. | 08-29-2013 |
20130287609 | ARRANGEMENT FOR THROTTLING A FLUID FLOW, AND CORRESPONDING PISTON PUMP FOR DELIVERING FLUIDS - 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. | 10-31-2013 |
20140030125 | SPRING ELEMENT AND CORRESPONDING PISTON PUMP FOR DELIVERING FLUIDS - A spring element includes a disc-shaped basic body, in which at least one spring bridge is inserted. The basic body has at least one dynamic throttle point to throttle a fluid flow. The basic body has a resilient configuration in a region of the at least one throttle point. Accordingly, an opening cross section of the at least one throttle point is configured to be set variably depending on a pressure difference. | 01-30-2014 |
20140030127 | VALVE, IN PARTICULAR AN OUTLET VALVE OF A HYDRAULIC PISTON PUMP - A valve, in particular an outlet valve of a hydraulic piston pump for delivering a fluid, includes a valve seat, a valve closing body, and a guide mechanism. A valve orifice is formed in the valve seat and has an inner wall. The valve closing body is arranged on the valve seat and is configured to selectively open and close the valve orifice. The guide mechanism is configured to guide the valve closing body relative to the valve seat and extends into the valve orifice. The guide mechanism has at least one fluid-conducting recess and at least one region configured to bear against the inner wall of the valve orifice to guide the valve closing body. | 01-30-2014 |
20140062177 | Hydraulic Unit of a Vehicle Brake System - In a hydraulic unit of a vehicle brake system having a first pump element, which is assigned to a first brake circuit, and a second pump element, which is assigned to a second brake circuit, the second pump element has a different delivery from the first pump element. | 03-06-2014 |
20140314349 | Electric Motor - An electric motor includes an armature shaft which is mounted in at least one floating bearing. The floating bearing comprises a bearing inner ring, which is positioned on the armature shaft, a bearing outer ring, which is received in a bearing seat, and a fluid pump for a vehicle fluid system having the electric motor. Lubricant disposed between the armature shaft and the bearing inner ring forms a hydrodynamic lubricant film and generates a constant relative movement between the armature shaft and the bearing inner ring. | 10-23-2014 |
