Latest Patents

One of his latest patents is a seal for a plug-in connection. This elastomeric seal effectively seals a pipe held in a push-in part of a plug-in coupling. It ensures a secure fit against the cylindrical interior surface of the housing, providing a reliable connection. The design features an outward-facing annular lip that maintains contact with the housing and a radially inward-facing annular lip that secures the pipe. This innovative seal simplifies assembly and creates a non-releasable connection, enhancing the overall efficiency of the plug-in coupling.

Another significant patent by Riess is a throttle device for hydraulic adjustment devices in motor vehicles. This device is strategically placed in the hydraulic line to establish various throttle resistances for fluid flow in both directions. The throttle device includes a disk with at least one boring or passage channel, which moves back and forth as fluid flows. This economical design allows for effective control of fluid dynamics within hydraulic systems.
