摘要： 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.

摘要： The invention relates to a piston pump for conveying a fluid, in particular in a vehicle brake system. The piston pump has a cylinder and a piston movably disposed in the cylinder. A restoring element preloads the piston, and a drive unit for actuates the piston in the cylinder to pump the fluid into a pressure chamber formed in the cylinder. The piston is embodied by a first piston par and a second piston part. The first piston part is a cylindrical body, which can be moved by the drive unit. The second piston part form the piston base, in which four radial inlet openings and one axial connection opening for communication with the pressure chamber are disposed. A flange for the disposition of a seal is disposed on the outer circumference of the piston base element. The openings are simple to make in the face ends and circumferential regions of the second piston part.

摘要： The invention relates to a piston pump with a piston, which is guided so that the piston can move axially in a liner that has been inserted into a pump housing and is driven into a reciprocating stroke motion by means of a cam that is driven to rotate. The invention uses a liner that is manufactured as an injection-molded plastic part. The plastic liner has advantages with regard to manufacture, damping behavior when there are pressure changes, and noise generation. Furthermore, the invention proposes affixing a filter integral with the liner when the liner is injection molded.

摘要： The invention seeks to reduce structure-borne sound emissions of the reciprocating piston pump. The reciprocating pump is includes an outlet valve, which has a valve seat and a valve closing body that is received in a hollow space and is loaded by a closing spring. One outlet bore radially originates at the circumferential region of the valve seat and branches off from the hollow space. The opening of the outlet bore toward the hollow space extends at least approximately between the valve seat and the end toward the closing spring of the gap of least cross section, which is formed between the valve closing body and the inside circumference of the hollow space. As a result, a slowed opening motion of the valve closing element is attained, in which opening motion an opening gap opens up that has its largest flow cross section in the region of the outlet bore. The supply flow, which increases slowly as the outlet valve opens, results in a slowed force variation speed in the drive train of the reciprocating piston pump and a reduced emission of structure-borne sound. The pressure fluid pumping device may be used for instance in hydraulic motor vehicle brake systems having an anti-skid system and/or traction control system.
