Abstract: In a diesel engine provided with a diesel particulate filter 81 and an exhaust throttle valve 9, noise is decreased that is produced when the exhaust throttle valve is returned back to the fully opened state after a diesel particulate filter 81 has been regenerated by oxidizing and removing the particulate matter deposited thereon. The exhaust system of the diesel engine is equipped with the diesel particulate filter 81 and a catalyst 82 on the upstream thereof, and is further equipped with the exhaust throttle valve 9 on the downstream. The diesel particulate filter 81 is regenerated by operating the diesel engine in a state where the exhaust throttle valve 9 is opened to a small degree. When the regeneration has finished, the diesel engine is run at a decreased rotational speed and, thereafter, the exhaust throttle valve 9 is returned back to the fully opened state. When the engine is run at a decreased rotational speed, the pressure in the exhaust system decreases making it possible to greatly decrease the noise that generates at the time of the opening of the exhaust throttle valve 9. In a diesel engine provided with a diesel particulate filter 81 and an exhaust throttle valve 9, noise is decreased that is produced when the exhaust throttle valve is returned back to the fully opened state after a diesel particulate filter 81 has been regenerated by oxidizing ...more ...less

Abstract: A lobed exhaust diffuser apparatus, system, and method configured to cool exhaust gases from an internal combustion engine comprises a diffuser having a proximal end, configured to receive exhaust gases from the engine, and a distal end, configured to expel the exhaust gases into the atmosphere. A plurality of lobes are disposed on the distal end such that at least a portion of the exhaust gases pass through the lobes, increasing the interaction surface area between the exhaust gases and the atmosphere, allowing for more rapid diffusion and entrainment between exhaust gases and atmospheric gases, resulting in more rapid cooling of the exhaust gases.

Abstract: To provide an expansion valve having a low-pressure passage that is bent at right angles therein, which is reduced in untoward noise and noise of the flow of refrigerant generated when the refrigerant passes through the low-pressure passage. In an intersecting portion of a low-pressure passage, the axis of a port for introducing refrigerant returned from an evaporator, and the axis of a port for guiding out refrigerant having passed through a body block to a compressor are orthogonal to each other. A hole is formed in the body block in a direction of insertion of a shaft that transmits a driving force from a power element to a valve element, and a holder for holding the shaft. When holes coaxial with the ports, respectively, are formed by drills having the same diameter as that of the hole, the holes are formed in a manner such that the tip of one drill does not extend beyond the hole formed by the other drill, to make inner walls on an outer peripheral side along which refrigerant flows at an increased speed, smoothly continuous, without forming any recess or edge portion having a boundary portion with an angle equal to or smaller than a right angle.

Abstract: A drum-type washing machine includes a washing water supply apparatus providing a liquid passage from a water outlet of a detergent reservoir to an inner space of a tub. The washing water supply apparatus employs a bubble dissipation device for preventing bubbles generated in a tub from reaching an inlet bellows and entering a detergent reservoir. The washing water supply apparatus includes a water supply duct formed at an upper part of the tub; an inlet bellows, one end of which is coupled to the water outlet of the detergent reservoir and the other end of which is connected to the water supply duct, for supplying a liquid to the tub; and a bubble dissipation device, vertically installed along the liquid passage of the washing water supply apparatus, for preventing bubbles generated in the tub from entering the detergent reservoir. The bubble dissipation device includes a float movably disposed in the washing water supply apparatus to travel a predetermined vertical distance along the washing water supply apparatus between a seated stated and a raised state, under a force of a forming air bubble, for blocking the liquid passage when a bubble is generated and allowing the liquid of the washing water supply apparatus to drain into the tub when no bubble is generated. An air escape hole having a small cross-section, for allowing air trapped by the float to escape slowly back into the tub, provides communication between the inner space of the tub and a space created when the float is in the raised state.

Abstract: The handcuff assembly includes a bow pivotally connected to a cheek plate frame assembly which includes a unitized frame that is die stamped from a single metal plate and which is overmolded with a polymer overmold. The unitized frame has interlocking tabs on folded side plates of a base frame. A removable lockset assembly for locking a pawl relative to ratchet teeth on the bow and including a slideable lock bar is received in the base frame. A key receiving structure on each side of the lockset assembly is provided for receiving a key and enabling the key to turned in one direction only for first unlocking a double-lock, which prevents movement of the bow in either direction and for secondly, completely unlocking the handcuff by moving the pawl away from the bow and against a spring mechanism. Beveled lock slots and keyways are provided in opposite flat side walls of the base frame for facilitating insertion of a handcuff key into the lockset assembly in the base frame.

Abstract: A lock system is provided including a lock core and a token. The lock core comprises a core body, a lock actuator coupled to the core body for rotation about an axis, a blocking body, and a solenoid. The solenoid has a shaft that is movable between a first position in which the blocking body is locked to prevent rotation of the lock actuator about the axis and a second position in which the blocking body is unlocked to allow rotation of the lock actuator about the axis. The token is couplable mechanically to the lock actuator. The solenoid moves the shaft from the first position to the second position so that the blocking body is unlocked if the token has a valid access code.
