Abstract

A spray apparatus includes a spray device which indirectly controls the activation and deactivation of a pump in a remote pumping mechanism. The spray device includes a control assembly which is adapted to control the fluid flow through the device. The control assembly includes a button which is normally biased into engagement with a fluid passage and can be manually manipulated to allow fluid to flow through the passage. The fluid passage in the spray device is connected by a conduit to the pumping mechanism. The pumping mechanism includes a pump, a fluid reservoir, and a pressure sensitive switch mounted within a housing. When activated, the pump draws fluid from the reservoir and forces the fluid through the pressure sensitive switch and the conduit to the fluid passage in the spray device. The button in the control assembly can be manually manipulated to selectively allow fluid to flow through the fluid passage and out through a nozzle in the spray device in the form of a stream or spray. When the button is not manipulated, the increase in pressure in the fluid passage, the conduit, and the pressure sensitive switch causes the pressure sensitive switch to deactivate the pump.
