A lubrication dispensing apparatus for lubricating a device with moving parts includes a lubricant reservoir, a lubricant dispenser for dispensing lubricant from the lubricant reservoir, an ultrasonic detection module which detects the amplitude of ultrasonic energy emitted by said device when its parts are moving and produces an signal related thereto, and a control module which analyzes the amplitude of the signal from the ultrasonic detection module and, in response to a lubricate signal, causes the lubricant dispenser to automatically dispense lubricant onto the moving parts of the device until the signal from the ultrasonic detector indicates that the ultrasonic energy produced by the device has decreased to a particular level. The control module includes a programmed processor and a storage memory. The memory stores as a base value the value of the detected amplitude of ultrasonic energy when the device is operating properly. After receiving a signal to lubricate the device, the processor causes the dispenser to start the flow of lubricant to the device, compares the signal from the ultrasonic detection module when the parts are moving to the base value, and causes the dispenser to cease the flow of lubricant when the signal substantially decreases.

The present invention provides an assembly for dispensing a lubricant. The assembly comprises a housing with a cavity and a nozzle member connected to the housing. The housing further includes a lubricant passage connectable to a source of pressurized lubricant and a fluid pressure inlet passage connected to a source of fluid pressure. The assembly further includes a piston member having a predetermined configuration with a first side in fluid communication with the fluid pressure passage and a second side and having a piston cavity formed within. There is a first bore extending through the piston. A retainer member is connected to such first side of the piston member. A valve device is biased by an urging device against the first bore preventing grease from exiting. Another urging device biases the piston to such closed position. A push rod is disposed within the first bore and extends a predetermined distance beyond an end of the second side of the piston. When fluid pressure enters the cavity, it forces the piston to the left and the urging device forces the ball valve and the push rod to the left until the push rod contacts resistance. The piston member continues to move to the left for such predetermined distance until it also contacts resistance. The push rod thereby preventing the valve device from pressing against the piston bore and thus permits grease to flow. Grease passes through a second bore, is mixed with fluid pressure and is expelled as a spray from the nozzle member.
