The spool includes a cross-sectional area changing portion located at a position corresponding to the second surplus restriction. Therefore, the circuit structure is prevented from becoming complicated and the fluid force acting as a spool urging force is suppressed.

Abstract: Nearly all residential and commercial buildings in the United States contain systems for the collection, flow, and run off of rainwater and condensation. Most of that water is funneled into existing municipal drainage systems or simply diverted onto the adjoining ground, but away from the building structure. This invention adds to that system a means to capture and store some of that water. It is intended primarily for residential use, but could be used in commercial applications as well. The invention interrupts the flow of water traveling through the down spout and diverts a preset amount into a storage tank. An exit back into the existing down spout carries all water back into the drainage system over and above that stored in the tank. It contains a flow control system that can be set to force all water through the normal drainage system, this is primarily for cold weather climates where freezing would be a concern in the storage tank.

The housing is fitted with flanges or other connection structures for quick, easy and convenient attachment of the housing to a piping network in an air, nitrogen or other process drying system.

The brake power assist unit is connected via the brake valve to the control unit.

Abstract: A fuel supply system for a motor vehicle has two feed units arranged in a fuel tank. The feed units in each case feed fuel out of baffles to an internal combustion engine of the motor vehicle and to suction jet pumps.

Abstract: A hydraulic system for a vehicle including a distributor, or switch, valve for actuating at least two operational areas and supplying the two areas with sufficient amounts of hydraulic medium is provided. The distributor, or switch, valve preferably comprises a flow regulator valve and a solenoid valve, which function so that the supply of hydraulic medium to the steering system always has priority, ensuring that the vehicle is steerable in any situation. When the steering system is operational, the supply of hydraulic medium to other operational areas, such as the clutch and transmission systems, is completely blocked by operation of the switch valve. If, however, the clutch and transmission systems should require hydraulic medium during operation of the steering system, the switch valve allows a small portion of hydraulic medium to be supplied to the clutch and transmission as well.
