An effluent processing apparatus comprises a housing having an inlet port and a chamber. A coalescing element is located in the chamber and arranged coaxially with the inlet port. The coalescing element has pleats in a predefined pattern of paths arranged to separate oil and water from an effluent mixture containing air, oil, and water. The effluent mixture flows into the inlet port along an axis of the coalescing element. The effluent mixture is deflected by a portion of the housing to flow perpendicular to the axis along major surfaces of the pleats to separate oil and water from the effluent mixture.

Effluent processing apparatus and method for a vehicle air brake charging system

An effluent processing device includes an input port to receive an effluent mixture containing air, oil, and water. One or more baffles are positioned between the input port and at least one air outlet to deflect the effluent mixture to assist in separating the oil and the water from the air. A member positioned below the one or more baffles selectively allows only oil of the separated oil and water to pass from a first side of the member through openings in the member to a second side of the member. A sump is arranged to receive and retain the oil on the second side of the member as the oil passes from the first side to the second side. The effluent processing devices includes at least one air outlet through which air is exhausted to atmosphere.

Effluent processing apparatus for a vehicle air brake charging system

An effluent processing apparatus comprises a separator device arranged to receive an effluent mixture to separate oil and water from the effluent mixture and thereby to provide clean air. A member selectively allows either only oil or only water of the separated oil and water to pass from a first side of the member through openings in the member to a second side of the member. A sump is arranged to (i) receive and retain the oil on the first side if only water passes from the first side to the second side, and (ii) receive and retain the oil on the second side if only oil passes from the first side to the second side. Clean air from the separator device is exhausted through an air outlet to atmosphere, and water is drained through a water outlet to atmosphere.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus comprises an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus also comprises a spiral-shaped effluent channel having a portion of decreasing channel width disposed between the inlet port and the outlet port. The spiral-shaped effluent channel is provided for increasing velocity of an effluent stream as the effluent stream flows through the decreasing channel width portion of the spiral-shaped effluent channel.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus has an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus further has a quadric surface defining an effluent flow chamber that is connected in fluid communication between the inlet port and the outlet port. The quadric surface is provided for extracting contaminants from an effluent stream as the effluent stream flows from the inlet port along the quadric surface to the outlet port.

Air dryer

An oil separator for use in a vehicle air system includes a recycling valve for removing coalesced oil. The recycling valve may include a piston movable in a cylinder in response to a control air pressure to open the recycling valve and thus drain coalesced oil from a sump under the influence of residual air pressure in the sump. The separator may include a fixture for mounting the separator to a vehicle, including a plurality of ports extending from an inlet port for directing air into the cartridge with a combined flow area at least equal to the flow area of the inlet port. The plurality of ports preferably extend at a right angle to the direction of flow of air through the inlet port. A safety relief valve on the separator releases air when the pressure exceeds a predetermined pressure.

Oil separator for vehicle air system

A module includes a reservoir having at least three chambers for storing compressed air for a vehicle air supply system, and a mounting assembly for supporting the reservoir on the vehicle. The chambers are separate from each other internally. The reservoir includes external connections, such as air lines or piping, for interconnecting the three chambers. The mounting assembly includes a bracket having a support surface. A bracket liner is received on the bracket between the support surface and the outer side surface of the reservoir. The reservoir may also include a purge chamber and an air dryer, as one unit, supported on the vehicle by the mounting assembly.

Air system module including reservoir and mounting structure

A serviceable filtering oil removal cartridge for use in a compressed air assembly of a vehicle air brake system includes a housing having a first end and a second end. A filtering element is disposed within the housing for agglomerating and removing oil from compressed air entering the oil removal cartridge. A load plate is disposed within the housing for supporting the filtering element. The load plate includes a connecting portion dimensioned to allow the oil removal cartridge to be removed and installed as a single unit. The connecting portion is preferably a threaded annulus. A thermal vent can be included, wherein pressure is released from the oil removal cartridge upon reaching a threshold temperature.

Spin-on filtering oil removal cartridge

A valve assembly for use in an air brake system is provided. The assembly includes a modulator housing, a valve assembly, and a clamp for holding the valve assembly in an operative position on the modulator housing. One leg of the clamp is fit over retaining bosses on the housing. Another leg of the clamp is bent or advanced toward a retainer that cooperates with a retaining opening on the leg to maintain the clamp in a tensioned state and secure the valve assembly to the modulator housing.

Clamp assembly and method

A modulator relay valve assembly for selectively controlling brake application to an associated brake chamber is provided. The modulator relay valve assembly comprises a housing having a supply port, a delivery port, a control port, and an exhaust port. A piston is received in the housing defining a control volume in communication with the control port and is movable to control communication among the supply, delivery, and exhaust ports. A quick release valve with a direct passage to atmosphere communicates with the control volume, allowing contaminants to be expelled form the control volume during service and ABS braking. The quick release valve is biased toward an open position allowing communication from a control volume to atmosphere during service brake and ABS brake applications to decrease a pressure exerted by the control volume on the piston.

Modulator relay valve assembly and method

A single piece metal clamp is provided for. The clamp includes an upper portion having a cylindrical section and a cross member section integrally connected through spaced apart left and right legs. The clamp also includes a lower portion having a base with a plurality of through holes. The upper portion and lower portion are integrally connected by a pair of spaced apart left and right legs, each leg having a corresponding right angle formed therein.

Solenoid clamp

First and second collars cooperate with first and second seal members separated by a retaining ring assembled onto a valve piston. The collars selectively engage the valve housing at one end and the retaining ring at the other end to limit the travel of the piston between first and second positions. Moreover, the assembly offers a cost effective alternative to the bonded rubber seals provided on known piston arrangements.
