Abstract: A method is provided for designing and producing fiber-reinforced polymer (FRP) pistons. Pistons made with FRP have a lower mass than prior art metal pistons conferring advantageous engine efficiency and stability. FRP pistons also increase the thermal efficiency of engines by having a lower thermal conductivity, with tighter piston-to-bore clearance, and/increased air-fuel ratio than pistons of metal. The technical parameters of the piston are identified, and a piston body blank is produced. The blank is then machined, a bearing surface for the pin bore is created, the piston blank is optionally coated, is optionally subjected to Heavy Metal Ion Implantation (HMII) treatment and is subjected to sodium silicate impregnation to produce the final pistons.

Abstract: A membrane system comprising a membrane and connecting elements for connecting the membrane to a membrane pump for conveying a fluid, which membrane pump has a drive shaft designed for an oscillating translatory movement perpendicular to the plane of the membrane during operation of the membrane pump and has an external thread at an end portion for engagement with the membrane system by screwing. To ensure a secure and torque-proof connection between the membrane and the connecting element to be screwed to a drive shaft, the connecting elements comprise a threaded socket, a thrust ring and a thrust plate.

Abstract: A cylinder head for a pump. The pump includes a piston and a cylinder block at least partially defining a cylinder chamber receiving the piston. The cylinder head is couplable to the cylinder block. The cylinder head includes an inlet manifold formed as a single piece, an outlet manifold formed as a single piece separate from the inlet manifold, and a pressure chamber positioned fluidly between the inlet manifold and the outlet manifold formed as a single piece separate from the inlet manifold and separate from the outlet manifold. The pressure chamber is formed of a first material, and at least one of the inlet manifold and the outlet manifold is formed of a second material different than the first material.
