Abstract: A governor system is provided that includes a governor having an actuator, and a coupler link configured to couple at a first end to the actuator and at a second end to a throttle of an engine being controlled. One or more mechanical characteristics of the coupler link, the throttle, an actuator arm of the actuator, or some combination thereof, are specific to the engine and configured such that each position of the actuator causes a given output of the engine independent of particular characteristics of the engine.

Abstract: A portable system of inter-connected smaller and larger canisters for near simultaneous vacuum and liquid transfer free from any external power. Captured vacuum in the canisters is employed for waste liquid extraction and a subsequent pressure transfer may take place without any liquid being exposed to the atmosphere. A mechanical manifold is adapted to receive the canisters, and one or more canisters may be physically connected to the manifold and are left in place as a user drives to another site location. An intermediate canister in the system is fitted with either manual or a self tending valve for the vacuum and pressure modes of the system.

Abstract: A fuel regulator receives fuel from a fuel pump at essentially constant pressure and reduces the pressure of the fuel to a constant low value in response to a predetermined high to moderate vacuum in an inlet manifold of an internal combustion engine, the vacuum corresponding to low or moderate load. At high load the regulator supplies fuel at a pressure proportional to absolute manifold pressure. At low to moderate loads the fuel at low pressure passes into the float bowl of a carburetor when a float controlled needle valve opens in response to a low level of fuel in the bowl as fuel is burned in the engine. The low pressure does not unseat the needle valve and supply an excess of fuel to the bowl. At high loads, the fuel pressure to the bowl is adequate to supply the increase rate of fuel such loads demand. As a result, the engine operates lean at low to moderate loads and richer at high loads. The regulator has a first diaphragm controlled valve.
