  • Patent number: 9366249
    Abstract: 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.

  • Publication number: 20160108900
    Abstract: A piston pump for a traction-controlled hydraulic vehicle braking system includes a pump piston and an annular piston that is arranged as a second piston in a resiliently loaded manner on the pump piston. As the delivery pressure increases, a resilient element is compressed and a stroke of the second piston is shortened so as to reduce a delivery quantity. This configuration enables a higher delivery pressure to be achieved for a given driving force. With low delivery pressure, the pump piston and the second piston deliver together so as to achieve a rapid build-up of pressure.
