摘要： A pressure relief valve (12) for relieving air pressure from a passenger compartment (14) of a vehicle (10) includes a base (18) having a peripheral portion (30). A central opening (42) extends through the peripheral portion (30). The pressure relief valve (12) also includes a plurality of flaps (74) for closing the central opening (42) of the base (18). Each flap (74) has an outer end (82) connected with the peripheral portion (30) of the base (18) and an inner end (80) that is movable relative to the peripheral portion (30) and the other flaps (74) for enabling airflow through the central opening (42). Each flap (74) has opposite surfaces (76 and 78) against which air pressure acts. Differential air pressure acts on the opposite surfaces (76 and 78) causing the flap (74) to move to enable airflow through the central opening (42).

摘要： A controlled weight-lowering device is presented which allows an individual to descend from a building at a predetermined rate of descent. The device can be permanently attached to the building or it can be portable. The device has an outer bracket which is securely attached to the inside of the building. Rotating about a shaft attached to the bracket is a cylindrical winding drum. The drum has a rope wound around it that is attached to a harness. The individual puts on the harness he desires to descend. Inside the winding drum is an inner gear pump and valve mechanism which is surrounded by an oil reservoir. Oil is allowed to go into the gear set chamber and circulates past the gears. The rate of flow of the oil out of the gear set chamber is regulated by a spring biased tapered piston. As the strength of the spring biasing is set on the piston, the rate of flow of oil within the gear set chamber is regulated. Because the gear set is connected to the cylindrical axis of the winding drum, controlling the rate of flow of oil, which controls the rate of rotation of the gears, also controls the rate of rotation of the drum.
