The present invention pertains to a plant watering system that is particularly suited for a plant container with a reservoir of water below the plant. The watering system uses a pilot controlled sequence valve to maintain the water level of the reservoir. The sequence valve includes a diaphragm that is pneumatically coupled to a pilot port fixed to the reservoir and submersed in the water. When the water level in the reservoir reaches a lower limit, the reduced pressure on a diaphragm causes it to open a pathway for water to flow from a water supply to the reservoir. When the water level reaches an upper limit, the increased pressure on the diaphragm causes it to close that pathway and shut off the water flow. The water supply can be an elevated tank or the pressurized water system. A pressure regulator can be used to lower the water pressure at the intake of the sequence valve. A nozzle controls the flow rate of water into the reservoir.

Liquid level maintaining device

A fluid pressure regulator is disclosed including a valve body and a control body sealed within a tubular outer housing. The valve body has a supply chamber and an output chamber separated by a valve wall. A valve rod extends through the valve wall with a seal unit therebetween for selectively connecting a passageway associated with the valve rod between the supply chamber and the output chamber. The output chamber has a movable wall connected to the rod. A control chamber is secured within the tubular housing in spaced relation to said movable wall with the space between the movable wall and the control chamber connected to atmosphere. The control chamber has a control rod with an adjustable bias spring urging the rod outwardly into engagement with the movable wall. A balance pressure passageway is formed by a lateral passageway from the supply chamber and from the control chamber with a passageway formed between the bodies and the tubular housing to connect said lateral passageway and maintain both chambers at the same pressure. The rod is formed in association with a movable sealing wall and seal member to provide various passageway constructions.
