Embodiment Construction

[0019] The following detailed description of the invention will explain the general principles of the invention, examples of which are further illustrated in the accompanying drawings. In the drawings, the same reference numerals indicate the same elements or functionally similar elements.

[0020] now refer to figure 1 , illustrates an exemplary schematic diagram of a turbocharger system 10 for an internal combustion engine 12 . In one embodiment, internal combustion engine 12 is a compression ignition (“CI”) or diesel engine of vehicle 1 , however, it should be understood that other types of engines, such as spark ignition (SI) or gasoline engines, could equally be used. The turbocharger system 10 may include an exhaust gas driven turbocharger (“EDT”) 20, a turbine bypass valve or wastegate 26, and a pressure relief valve 30, wherein the exhaust gas driven turbocharger (“EDT”) ”) 20 has a turbine section 22 and a compressor section 24. Exhaust casing 18 of EDT 20 contains...

Abstract

The present application discloses a valve assembly, and the valve assembly includes an evacuation device and a pressure relief valve. The evacuation device includes a suction port to selectively apply vacuum. The pressure relief valve has an open position and a closed position, and includes an inlet, an outlet, a piston that translates within the chamber, and a boost chamber. The piston includes a first end and a second end. A plenum is fluidly connected to the suction port of the evacuation device and is defined in part by the first end of the piston. If vacuum is applied to the boost chamber, the piston translates within the boost chamber towards the open position.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 62 / 025,548, filed July 17, 2014. technical field [0003] The present invention relates generally to pressure relief valves in which an evacuation device is used to provide a vacuum to actuate the pressure relief valve to an open position. Background technique [0004] Internal combustion engines are used in a variety of applications such as, for example, passenger and industrial vehicles, marine, stationary and aerospace applications. There are generally two dominant ignition cycles, commonly referred to as the gasoline and diesel cycles, more formally referred to as the spark ignition (SI) cycle and the compression ignition (CI) cycle, respectively. [0005] Exhaust-driven turbochargers can be used to increase the power output and overall efficiency of internal combustion engines. Specifically, exhaust energy may be used to drive a turbine. A turbocharger includes a...
