Title: Accelerator linkage for heavy vehicle with fuel injection pump - has hydraulic servo to alter linkage length when changing gear
IPC: G05G1/46
Filed: 1973-08-03
Abstract: The servo consists of a housing containing a cylinder with an outer piston ring and a central internal projection. The cylinder ends are each have ball links to connect respectively to the accelerator pedal and the fuel pump control rod. The cylinder contains a piston consisting of two sprung centering pistons arranged each side of the central projection ring. Fluid unions to each piston chamber lead respectively to magnetic valves in communication with a hydraulic pressure source. When a gear is changed, one of the solenoids is excited to cause the fluid pressure to enter the piston chamber to move the piston to the right which has the effect of altering the linkage length so that the pump delivery rate falls. After the gear change, the piston spring returns the piston to normal and the linkage acts as a rigid connection. On changing to a lower gear from a high gear, the opposite solenoid is excited and the pump delivery rate increased. The advantage being that a non synchronised gear box may be used.

Title: Water additive metering device - with flowmeter driving metering pump in by pass and control element actuated by flowmeter pressure drop
Inventor: LANG HELMUT
IPC: G05D11/00
Filed: 1974-11-29
Abstract: A device for the feed proportioning of liquid media into the water flowing in a water main uses a motorized flow-meter to drive a metering pump. The flowmeter is arranged in a bypass to the water main and its control element. The latter is opened and closed as a function of the pressure difference across the flowmeter by a double acting piston which actuates a spool valve for a spring-loaded single acting piston on the control element. The flow meter can thus be small enough to meter correct amounts of additives even at very small flow rates in the water main when large flow-meters do not register at all.
