Abstract: A fluid flow control system 40, 80 for use in an automotive wash system containing a fluidic, shear, or jet nozzle 50 for washing lens components, mirrors and headlamps with a supply fluid flow rate of between 1 and 2500 mL/min with a supply pressure of between 1 and 80 psi is fluidly connected through a pressure control device (PCD) or flow regulator 140, 180, in such a way that flow to the nozzle does not exceed 90% of the nominal flow rate without the PCD for supply pressures between 30 and 60 psi, or with a lower target flowrate for the same pressure range. The PCD 180 is an elastomeric body incorporating multiple flexible tabs in the fluid flow path responsive to flow rate and pressure to vary the area of the flow path. An annular spacer positioned below and in engagement with the flexible tabs regulates the flexing of the tabs.

Abstract: A hydrostatic transaxle (IHT) comprises a hydrostatic transmission (HST), an axle, a deceleration drive train, a first housing member, and a second housing member. The HST includes first and second hydraulic displacement units fluidly connected to each other. The first hydraulic displacement unit has a pump shaft for receiving power from a prime mover. The second hydraulic displacement has a motor shaft. The deceleration drive train is interposed between the motor shaft and the axle. The first housing member supports the HST and the deceleration drive train, and has an opening through which the HST and the deceleration drive train are installed into the first housing member. The second housing member is joined to the first housing member so as to serve as a lid for covering the opening of the first housing member after the HST and the deceleration drive train are installed in the first housing member so as to be supported by the first housing member.
