Abstract: A pressure equalization device connects to a port on an endoscope and equalizes the pressure within the endoscope to an environment thereabout. An outlet check valve allows flow out of the port and blocks flow into the port. A filter may be provided for preventing known chemical agents from entering the port. If the agent is hydrogen peroxide, the filter preferably comprises a catalyst, such as copper wool, for decomposing the hydrogen peroxide into water and oxygen. An inlet check valve may also be provided to communicate with the endoscope port and allow flow into the port in response to a downstream pressure gradient exceeding a predetermined value.

Abstract: An oil cooler for a final drive unit is disposed under a vehicle floor and installed on a rear elevated portion of a rear floor panel and under a rear seat. In one embodiment, bracket arrangement for installing the oil cooler under the vehicle floor serves not only as a support for the oil cooler but as a deflector or an air introducing device for efficiently introducing air to the oil cooler.

Abstract: Herein disclosed is an arrangement of a canister-used emission control system in a motor vehicle. The canister is positioned within a safety zone which is enclosed by mechanically rigid members of the motor vehicle.

Abstract: A two-shift throttle control system for an automotive engine, comprising a lever to be actuated by an accelerator pedal, a pedal-actuated control cable anchored at one end to the pedal-actuated lever and pulled toward the lever when the pedal is depressed, a throttle actuator unit responsive to a selected vehicle speed and operative to produce a mechanical force variable with the selected vehicle speed, an automatically-actuated control cable connected at one end to the throttle actuator unit, a throttle actuator lever movable with the throttle valve in the fuel supply system of the engine, a throttle drive cable anchored at one end to the actuator lever, a stationary shaft, and first and second rotatable members rotatable on the shaft independently of each other, each of the pedal-actuated control cable and throttle drive cable being anchored at the other ends to the first rotatable member for driving the rotatable member to turn in one direction about the shaft when the accelerator pedal is depressed, the a
