摘要： A filter element includes a first end cap, a second end cap, and a ring of filter media disposed between the first end cap and the second end cap. The ring of filter media circumscribes a central cavity. The filter element also includes an air-bleed conduit axially extending through the central cavity. The air-bleed conduit includes a first portion integrally formed with the first end cap and a second portion integrally formed with the second end cap. The second portion is configured to fluidly connect to the first portion.

摘要： A method for retrofitting an operating fuel delivery system of a vehicle. The method includes obtaining a vehicle having an operating fuel delivery system, which includes an interconnected fuel tank, a fuel pump and an engine. Obtaining an air separator configured to be attached to the fuel delivery system at a connection point wherein the fuel pump and the engine are in direct fluidic communication and also obtaining attachment means for connecting the air separator to the fuel delivery system by fluidically mounting the air separator at the connection point wherein the fuel pump and the engine are secured in direct fluidic communication.

摘要： A fuel delivery system for an internal combustion engine system is described herein. The fuel delivery system uses one or more bidirectional purge components to provide for bidirectional purging of a fuel from at least a portion of the fuel delivery system. The bidirectional purge components provide for a fuel delivered using the fuel delivery system to be purged into the directional purge component in more than one fluid flow direction. When a differential pressure is applied across the bidirectional purge component, the fuel is purged into an inlet and an outlet of the bidirectional purge component, leaving the component through a purge outlet and into a tank. The differential pressure can be generated using a pressured fluid such as nitrogen or a pump downstream of the purge outlet.

摘要： The present application discloses a fuel-water separation filter element capable of exhausting gas, and a filter. The filter element includes a filter element frame, a filter medium, and an exhaust valve assembly. An upper end cover and a lower end cover are arranged at an upper end and a lower end of the filter element frame. The upper end cover is provided with a recess surface along an axial direction of the filter element frame. The exhaust valve assembly includes a valve seat and a valve element. The valve seat and the recess surface form an exhaust cavity communicating with the inside of the filter element. The exhaust valve assembly in the present application can effectively exhaust gas in the filter.

摘要： A fuel delivery system for controlling an inlet pressure of a prime mover in a transport climate control system is provided. The fuel delivery system includes a fuel tank, a pressure regulator, a pump disposed downstream of the fuel tank, a first filter disposed downstream of the pump, and the prime mover disposed downstream of the first filter. The prime mover is located above the fuel tank in a vertical direction. The pump is configured to provide a first fuel flow through the first filter. The prime mover is configured to accept a first portion of the first fuel flow and is configured to provide a return fuel flow. The pressure regulator is disposed downstream of the first filter. The pressure regulator is configured to accept a second portion of the first fuel flow, and to accept a pressure of the return fuel flow as a reference pressure.
