A compressor system can include a lubricant injection system useful to supply lubricant to an airend. The compressor system can include a variable lubricant flow valve which can be regulated by a controller on the basis of operating conditions of the compressor system. In one form the compressor system also includes an oil separator and/or an oil cooler with or without a thermal control valve. The controller can have one or more modes of operation, including a mode in which the controller regulates the flow of lubricant to the airend to increase an internal flow area of the valve when the airend is operated at an unloaded or loaded condition. In some forms the controller can regulate the lubricant flow valve and/or the thermal control valve and/or the lubricant cooler.

Airend having a lubricant flow valve and controller

A compressor is disclosed which can include a first stage and a second stage. In one form the compressor includes contact cooled compressor stages. The compressor can include a rod useful to inject a lubricant for purposes of cooling/lubricating/sealing the rotating components of the compressor. In one form the rod is an elongate rod with openings which permit a lubricant such as oil to be injected. The injected oil can be atomized via the openings. The rod can be positioned in the interstage space between the first and second stages, and can include a variety of openings.

A computer may display on a graphical user interface (GUI) a component library including a set of components relating to a compressed air system. The GUI may have a modeling interface for configuring a virtual model using the set of components. The computer may simulate the virtual model to determine one or more optimizations to the compressed air system. The computer may also determine the cost of implementing the compressor system optimization.

A compressor system can include a lubricant injection system useful to supply lubricant to an airend. The compressor system can include a variable lubricant flow valve which can be regulated by a controller on the basis of operating conditions of the compressor system. In one form the compressor system also includes an oil separator and/or an oil cooler with or without a them al control valve. The controller can have one or more modes of operation, including a mode in which the controller regulates the flow of lubricant to the airend to increase an internal flow area of the valve when the airend is operated at an unloaded or loaded condition. In some forms the controller can regulate the lubricant flow valve and/or the thermal control valve and/or the lubricant cooler.

A damping device for an exit device that is configured to resist high velocity movement a latch assembly relative to a baseplate assembly. Pivotal displacement of a bell crank during typical operation of the exit device may cause a protrusion of the bell crank to exert a pulling force on control linkage element that is coupled to a connection link of a latch assembly and a spring damper element of the damper device, thereby operating the latch assembly while also generally by-passing the damping effect of the damping device. When high velocity movement is imparted on an entryway device associated with the exit device, the damper device resists high velocity movement of the latch assembly relative to the baseplate assembly, thereby at least attempting to prevent the latch assembly from moving independently of the baseplate assembly so as to prevent unlatching of a latch of the latch assembly.

A compressor conduit layout system is disclosed which includes a handheld device operating in conjunction with a computer based application to obtain data of a conduit system and display a model of the system. The handheld device can include a range finder, a designator used to designate a point of interest so that the range finder can determine a distance between the point of interest and the handheld device, as well as a sensor(s) useful to determine an orientation of the handheld device. The computer based application can include a pallet-and-canvas type application which displays a computer model of the conduit system. The compressor conduit layout system can use or can alternatively include an indoor positioning system useful to determine the position of the handheld device.
