Latest Patents

One of Holtermann's latest patents is a fluid metering pump designed for dispensing accurately measured amounts of fluid. This pump features a one-way check valve on both the upstream and downstream sides of a variable volume pump chamber. The flow passage allows fluid communication from the upstream check valve to the pump chamber, which is accessed through a centrally located opening surrounded by a valve seat. The pump chamber's wall consists of a flexible diaphragm attached to a solenoid actuator's plunger. This design ensures that, in the absence of solenoid excitation, the diaphragm prevents fluid flow by sealing against the valve seat. The materials used in the pump are chemically inert and non-corrosive, allowing for precise dispensing of fluids in increments as small as 10 microliters.

Another significant patent is a check valve that permits flow in one direction only, suitable for controlling corrosive or chemically active fluids. This valve comprises a body made from an inert substance, defining inlet and outlet flow passages with a central chamber. An elastomeric disc traverses the central chamber, and the sealing engagement of the disc with the valve seat prevents flow. When the pressure differential across the disc exceeds its resilience, the disc deforms, allowing flow through the valve. The design includes support stops to prevent the disc from being forced into the inlet flow passage under high back pressure.
