摘要： An automatic air brake system for accelerating the exhaustion of the pressure in the brake line of a train for more rapidly applying the brakes on all the railway vehicles. A flow rate detector connected to the brake line of the locomotive to detect the flow of air in the brake line. A pilot chamber of a relay valve is supplemented when a flow signal from the flow rate detector exceeds a predetermined value and the supplementation is stopped when the flow rate drops below a predetermined value. The pilot chamber is exhausted in response to a brake application command and is pressurized in response to a brake release command. The relay valve includes an output chamber which is connected to the brake line of the locomotive, and the brake line pressurizes and exhausts the output chamber in response to the pressurization and exhaustion of the pilot chamber.

摘要： Several embodiments of induction systems for internal combustion engines that improve the charging efficiency, particularly at low speeds are disclosed. Each embodiment employs a plenum chamber upstream of the engine throttle valve and a reed type check valve admits air to the plenum chamber so as to improve charging efficiency at low speeds by maintaining an air flow in the induction system. In accordance with some embodiments, a supercharger is also employed which discharges into the plenum chamber upstream of the throttle valve. This arrangement minimizes pulsation effects from the supercharger being transmitted to the engine intake ports. In addition, the reed type check valve can be employed in many of the embodiments to bypass the supercharger under conditions when the supercharger is not generating any significant boost. The location of the reed type check valve relative to the plenum chamber and throttle valve of the engine minimizes pulsations from being transmitted from the intake ports back to the check valve. In several embodiments an air cleaner housing is formed integrally with the plenum chamber to afford a more compact assembly.

摘要： An automatic air braking system for a railway train having a flow detector for sensing the flow of pressurized air in the brake line during a brake release command time. A pilot chamber located in a relay valve which is pressurized when a signal from the flow detector exceeds a first predetermined pressure value and which stops the pressurization when the flow signal drops below a second predetermined pressure value. The brake line runs from the lead unit or locomotive of the train and through the railway vehicle or freight cars connected to and pulled by the lead unit or locomotive. The relay valve which is an automatic-lapping-type is located in the lead unit or locomotive in which the pilot chamber is exhausted in response to the reception of a brake release command. An output chamber, which is located in the relay valve, is connected to the brake line of the lead unit or locomotive. The output chamber is pressurized in response to pressurization of the pilot chamber and is exhausted in response to exhaustion of the pilot chamber, so as to accelerate the brake release operation along the length of the train.
