Abstract:
A sprung gate for a valve having an endless elastic band sandwiched between first and second gate members that each define an opening therethrough in an open position portion thereof, which collectively form a passage through the sprung gate. The first gate member includes a fastener connected to a fastener receiving member of the second gate member thereby securing the first and second gate members together as a unit. This sprung gate unit is operatively connected to an actuator for linear translation within a pocket of a conduit to control fluid flow through the conduit. This assembled device may be manufactured using spin welding to sealingly mate the conduit to a housing enclosing the actuator.
Abstract:
A cleaning composition is particularly suited for cleaning dirty intake valves. The cleaning composition includes a high solvency surfactant/solvent which has a Kb greater than 100 or polar Hansen solubility parameter greater than 6. The surfactant/solvent is combined with a carrier such as water or an organic carrier and a surfactant. A wetting agent may also be employed. The cleaning composition is added to the intake air as a mist as the engine is running. Aqueous and non-aqueous versions are disclosed.
Abstract:
Un système de fermeture pour circuit de gaz d'admission comprend un corps de vanne (10) et un élément d'obturation (11) variant entre une configuration d'ouverture et une configuration de fermeture bloquant la circulation de gaz d'admission. Il comprend aussi un actionneur (13) solidaire du corps de vanne (10) et assurant le déplacement de l'élément d'obturation (11) au moins vers l'une des configurations de fermeture et d'ouverture, un dispositif de détection de gaz et de vapeurs inflammables intégré au corps de vanne (10) et doté d'une unité de détection de gaz et de vapeurs (12) mesurant la concentration en au moins un gaz inflammable ou une vapeur inflammable prédéterminés et un module de commande communiquant avec l'unité de détection (12) et avec l'actionneur (13) pour assurer un pilotage de l'actionneur (13) en fonction de la mesure réalisée par l'unité de détection (12). Il est également décrit un procédé de test et un procédé de fonctionnement du système de fermeture.
Abstract:
A pneumatically actuated vacuum pump is disclosed, and includes a body defining a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap. The Venturi gap is located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. The pneumatically actuated vacuum pump also includes a first check valve fluidly connected to the Venturi gap and the suction port. The pneumatically actuated vacuum pump further includes at least one second gap located in the diverging discharge section of the body downstream of the Venturi gap. A second check valve is fluidly connected to the second gap.
Abstract:
An air intake system (30, 130) for a work vehicle (10) may include a filter assembly (32, 132) having a pre-cleaner (36, 136) and an air filter (38, 138). The filter assembly (32, 132) may define at least one outlet port (46, 146). The air intake system (30, 130) may also include an air valve (72, 172) movable between an opened position and a closed position and a blower (64, 164) coupled to the outlet port (46, 146) via a conduit (58, 158). The blower (64, 164) may be configured to create a vacuum within the conduit (58 , 158) such that particulates are removed from the filter assembly (32, 132) through the outlet port (46, 146). When the air valve (72, 172) is in the opened position, an airflow may be directed through the filter assembly (32, 132) in an intake direction from the pre-cleaner (36, 136) through the air filter (38, 138) and, when the air valve (72, 172) is in the closed position, the airflow may be directed through the air filter (38, 138) in a reverse direction.
Abstract:
An outboard motor unit (1) includes a first outboard motor (10) including a supercharger (16) that is located inside a first cowling (12) and supplies compressed air to a first engine (11), a second outboard motor (20) including a second cowling (22) and a second engine (21) housed in the second cowling, and an air passage (40) through which the air compressed by the supercharger of the first outboard motor is supplied to the second engine of the second outboard motor.
Abstract:
An intake device (2) and charge-air cooler unit for an internal combustion engine comprises an intake device and a charge-air cooler, wherein the charge-air cooler is integrated into the intake housing (13) in such a way that the flow direction of the charge air in the charge-air cooler is in-plane vertically to the component containing the apertures (5) via which the combustion air is conveyed the cylinder inlets in the cylinder head.
Abstract:
An intake assembly (100) for an internal-combustion engine (2) comprises one intake duct (104) for each cylinder (CY), which communicates with an airbox (106) that comprises, inside it, a filtering element (114). Each intake duct (104) communicates with the airbox (106) by means of a respective throttle body (108). A monitoring channel (120) connects the intake ducts (104) together and is configured for perturbing in a negligible way the dynamics of the fluid inside the intake ducts (104). Associated to said monitoring duct are sensors for monitoring the pressure inside the monitoring duct and consequently designed to send signals indicating the value of pressure (P) of the fluid taken in by the engine to an electronic control unit.
