Abstract: A vibration isolation system for compactly mounting a vibrating component, such as an air compressor, to an object, such as an air tank, is described. The system may include a rod and bumper system to isolate the vibrations generated by the air compressor from the vehicle or object that it is mounted to. A primary isolation subsystem may include a rod suspension design which consumes significantly less space than existing solutions. The rod is able to achieve equal spring rates in any direction.

Abstract: A push-to-connect coupling with integrated filtration is disclosed. In one aspect, the coupling comprises a tube support, a collet and a filter element. The coupling may include a seal. The coupling connects to a cavity, which may be a portable fitting. The cavity may be a connection on a separate device or system, such as an air tank or other devices. The filter element may be dome-shaped. The tube support is easily assembled with the cavity, for example by threading, to capture the filter element. The tube is connected to the coupling by pushing the tube over the tube support and through the collet. The collet interacts with a reduced diameter section of the cavity to apply a clamping force from the collet on the tube and secure the tube in place. The tube is easily removed from the cavity simply by pushing the collet farther into the cavity to remove the clamping force on the tube, and then pulling the tube out.

Abstract: An air spring bellows for an air spring. The air spring may be used in suspension systems for automobiles, trucks, buses, trains, and industrial machines, among other applications. The air spring includes an air spring bellows. The bellows includes a flexible elastomeric substrate. The substrate is formed of polyurethane. Polyurethane may be the sole elastomer, or the majority of the elastomeric material, in the substrate. The substrate may be translucent. The bellows may include reinforcements, such as fiber cords. Plies of the fiber cords may be arranged within the elastomeric substrate.

Abstract: A modular pressure vessel suitable for housing, storage, and/or supplying a pressurized fluid is disclosed. In one aspect, the modular pressure vessel comprises removable end-caps attached to each end of a center section. The center section includes longitudinal rails. In another aspect, methods for manufacturing the modular pressure vessel are described, including extrusion processes for the center section. The modular pressure vessel allows for various components to be easily swapped out or changed, such as the end-caps, or components easily installed and removed from inside the pressure vessel, such as a compressor and related components.
