Patent application number | Description | Published |
20130202465 | Piston Pump having an Inlet Valve - A piston pump includes a piston, a sealing element sealing the piston radially with respect to a cylinder, and an inlet valve arranged on the piston. The inlet valve includes a valve cage holding a closing member. The sealing element is integrally designed with the valve cage. | 08-08-2013 |
20130240773 | VALVE OF A PISTON PUMP WITH A CLOSING BODY - A valve of a piston pump, in particular for a hydraulic vehicle brake system, includes a closing body configured to be moved in an axially guided manner against a sealing seat. The closing body is formed in two pieces, which include a damping piston and a closing element inserted in the damping piston. | 09-19-2013 |
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 |
20130287610 | METHOD FOR PRODUCING A PISTON PUMP AND PISTON PUMP - A method is used to produce a piston pump having a housing and a piston subassembly. The piston subassembly is displaceably guided in the housing and has a first, rod-like piston element and a second, sleeve-like piston element. The second piston element is connected to the first piston element via a press fit. At least one transverse bore and a longitudinal bore are arranged in the second piston element. A stop edge for the housing is arranged on the second piston element. The piston subassembly also has an inlet valve, which includes a receiving element, in which an inlet valve spring and an inlet valve sealing element are arranged. The piston subassembly also has a corresponding inlet valve seat, which is arranged on the second piston element. While the second piston element is being machined, the press fit and the longitudinal bore are produced and/or finished in one step. | 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 |
20140030128 | PISTON PUMP HAVING A CYLINDER BARREL - A piston pump for delivering fluids includes a piston configured to be driven to perform a reciprocating stroke movement. The piston pump includes a cylinder barrel in which the piston is held in an axially displaceable manner. The piston pump also includes a displacement chamber which is arranged in the cylinder barrel between an inlet valve and an outlet valve. The outlet valve is arranged on a cylinder barrel base, and, on a side of the cylinder barrel base which faces away from the displacement chamber, an annular projection is formed. The annular projection is configured to surround an installation space for the outlet valve. | 01-30-2014 |
20140061438 | IMAGE SENSOR MODULE AND METHOD FOR PRODUCING SUCH A MODULE - An image sensor module includes an image sensor bearer and an image sensor, the image sensor bearer being fashioned as an injection-molded circuit bearer, and the image sensor being situated on the image sensor bearer, and the image sensor bearer including at least one holding device that is integrally formed on the image sensor bearer. | 03-06-2014 |
20140301876 | PISTON PUMP HAVING A HOLDER - A piston pump, in particular for a hydraulic assembly of an electronically controllable vehicle brake system, includes a cylinder element that has a pressure chamber with an outlet formed on the inside. The piston pump further includes an outlet-restricting element held on the outside of the cylinder element on a component by a first holder. | 10-09-2014 |
20140326090 | METHOD FOR PRODUCING A THREADED PART AS COMPOSITE COMPONENT, ROLLER SCREW DRIVE, LINEAR ACTUATOR, AND ELECTROMECHANICAL BRAKE BOOSTER HAVING SUCH A COMPOSITE COMPONENT - An electromechanical brake booster includes a hollow spindle and a hollow screw. Courses of thread are produced by deformation from metal and extrusion-coating them together with tubular supporting structures made of plastic. The hollow spindle and the hollow screw are produced as composite components. | 11-06-2014 |
