摘要： Devices for producing vacuum using the Venturi effect and systems, such as internal combustion engine systems, including the same are disclosed. The devices include a housing defining a suction chamber, a motive passageway converging toward the suction chamber and in fluid communication therewith, a discharge passageway diverging away from the suction chamber and in fluid communication therewith, and a suction passageway in fluid communication with the suction chamber. Within the suction chamber, a motive exit of the motive passageway is generally aligned with and spaced apart from a discharge entrance of the discharge passageway to define a Venturi gap, and the suction passageway enters the suction chamber at a position that generates about a 180 degree change in the direction of suction flow from the suction passageway to the discharge passageway.

摘要： Pressure piston actuators and systems for control of wastegate in a turbocharger pressure that include the pressure piston actuators are disclosed. The pressure piston actuator includes a housing defining a chamber and a pathway leading to the chamber, a piston disposed within the chamber, a rod connected to the piston by a ball-and-socket joint, and a spring disposed in the chamber to bias the piston, and hence the rod, into a retracted position. Then, when fluid is introduced into the chamber, the fluid applies pressure to the piston. Once the pressure overcomes the bias of the spring, the piston, and hence the rod, moves into an extended position. For the system, the pressure piston actuator has the connector on the end of the rod opposite the ball-and-socket joint connected to the valve portion of a wastegate of a turbocharger.
