摘要:
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.

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.

The disclosure relates to a pistol pump for delivering fluids comprising a piston, a cylinder element, and a pressure chamber arranged between an inlet valve and an outlet valve, The pressure chamber is closed off by a cover. The outlet valve comprises a closing body, a preload device which acts on the closing body, and a supporting mechanism configured to support the preload device. The outlet valve is arranged on the outer circumference of the cylinder element and adjusts a fluid flow conducted through at least one outflow opening between the cover and the cylinder element. The closing body is configured as a movable annular disk guided on the cylinder element, the inner diameter of which annular disk is matched to the outer diameter of the cylinder element.

In a valve, in particular an outlet valve of a hydraulic piston pump for delivering a fluid, includes a valve seat and a valve closing body. A valve orifice is formed in the valve seat, and the valve closing body is arranged on the valve seat. The valve closing body is configured to selectively open and close the valve orifice, and the valve closing body includes a sealing bead which forms a sealing fit with the valve seat when the valve orifice is in the closed state.

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.

A piston pump for delivering fluids includes a piston, a cylinder element and a pressure chamber which is arranged between an inlet valve and an outlet valve and is closed by a cover, wherein a throttling mechanism for throttling the fluid flow is provided in the fluid flow downstream of the outlet valve, and a vehicle brake system has a piston pump of this type. The throttling mechanism includes a movable annular disc which is guided on the cylinder element and the internal diameter of which is adapted to the external diameter of the cylinder element, wherein the axial travel of the annular disc sets a variable first throttle cross section.

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.
