摘要： A rotary air compressor driven by an electric motor and having a control system including a control circuit which enables the compressor to run in a modulated air flow mode of operation, shift automatically at a certain set process pressure to an unloading-reload mode of operation; and shift automatically when the compressor runs unloaded beyond a timed period to a condition in which the compressor is stopped but will automatically restart operating when the process pressure falls below a certain low setting and the tank pressure drops to a safe starting value. Also disclosed is a dual control system designed to provide automatic transfer from the modulation mode to unloading operation.

摘要： A portable compressor apparatus having a soundproofed and air cooled shell in which a combustion engine driven air compressor unit is confined. The mufflers for the engine are located externally of the shell in a soundproofed housing through which cooling air from the shell is circulated. Cooling air is drawn by a fan through openings at the front of the shell and blown straight through the shell to a series of vent channels defined by sound attenuating panels at the rear of the shell. The sound finally issuing from the apparatus is quieted, non-irritating and at an acceptable level.

摘要： A pavement breaker having a reciprocating piston hammer to pound a work steel, wherein a jacket about the tool provides a reservoir of constantly pressurized oil, which pressurized oil drives the hammer on a work stroke, operates a plunger to return the hammer, operates dampers to dampen excessive movement of the hammer beyond its usual impacting point, operates a dump valve to relieve the pressurized condition of the reservoir when the tool is lifted out of pressed relation to the work, and operates a ram to shift a control valve in one direction to interrupt reservoir oil flow to the hammer, the control valve being mechanically shiftable in the opposite direction by the hammer on a return stroke to reestablish reservoir flow to the hammer.

摘要： A completely assembled air shut-off control valve unit illustrated as fitted in a bore of a pneumatically powered nut runner in the path of air flow between the throttle valve and the motor. The unit is of capsule form defined by means of a shell in which the various components are confined. A cap closes over an open end of the shell through which end the various components may be withdrawn. The valve is of a piston and rod form having a spring load in association with an adjusting screw and travel nut means for adjusting the load of the spring upon the valve. Structural design of the valve, together with a valve guide serve to effect pneumatic balancing of the valve and consequent reduced friction in its movement.

摘要： A pneumatic load-balancing unit capable of automatically balancing pneumatically at a specific level any weight within the capacity of the unit following manual actuation of a control valve connected with a pressure air supply; and to allow this weight to be manually moved or floated with predetermined ease above and below the balance level within the stroke range of a piston carrying the weight. The unit includes a cylinder containing the piston upon the rod of which the weight is attachable. Air pressure in a reservoir connected in a closed circuit with the cylinder functions to counterbalance the weightloaded piston. Since the level of the piston will change with a change in the weight load, then in order to return the workloaded piston to its normal level, the control valve is manually opened. A system of valves automatically responds to pressure airflowing through the control valve to either admit increased pressure air or to relieve pressure air from the closed circuit as needed to return the piston to its normal balance level. The pressure in the closed circuit remains constant following restoration of the piston to its normal balance level and release of the control valve. The closed circuit normally permits free airflow between the cylinder and the reservoir except when the system of valves is caused to function, then it provides a restricted flow. The restricted flow develops back pressure which functions to snub movement of the piston so as to aid in bringing the piston to a stabilized condition. In a modified form, an arrangement between the control valve and the system of valves requires only a momentary opening of the control valve so as to initiate operation of the system of valves, after which the control valve may be released. The system of valves then functions automatically until the work-loaded piston is restored to its normal level.

摘要： A safety device to protect a rotor impeller in a centrifugal compressor from damage that might otherwise occur when the impeller, because of some fault, engages an opposed wall of its chamber. The device includes a hollow tubular body supported in the walls of the compressor. It has one end connected with a pressure switch arranged in a power control electrical circuit, and has an opposite abradable thin end projecting into the impeller chamber. The device is pressurized with fluid and, when its thin end is caused to be abraded away by the impeller, the pressure fluid will be dumped, causing actuation of the switch and consequent discontinuance of power to the compressor. The pressure fluid for the device may be supplied from the compressor system or from an external source. In condenser steam turbines, the tubular body of the device may be connected with a vacuum element and arranged so that when the thin end is abraded away the tubular body will become pressurized by the process fluid to cause actuation of the pressure switch.
