Patent ES-436430-A1 (ES)
Title: Axial flow fans
IPC: F04D29/36
Filed: 1975-04-09
Abstract: In an axial flow fan impeller, the natural frequency of vibration of the individual blades is increased by mounting each blade to the annular support rim or hub for swinging movement relative to the ring about an axis, which lies generally perpendicular to a radius passing through the mounting. For a given blade, the mounting enables the fan to be rotated at higher speeds with a corresponding increase in performance. The mounting also permits the use of thinner, lighter-weight blades for a given operating speed and this permits a reduction in the cross sectional area of the rim. If the impeller includes a mechanism for controlling the pitch of all the blades during operation, the use of lighter-weight blades reduces the stresses on the mechanism so that the design and strength of the latter does not tend to be a limiting factor on the maximum permissible speed for the impeller.

Title: Hydraulic brake booster having charging and check valves
IPC: B60T13/12
Filed: 1978-01-05
Abstract: A hydraulic brake booster includes a housing defining a pressure chamber and an inlet port communicating pressurized fluid to an accumulator and the pressure chamber. The housing includes a bore which slidably receives a charging valve and sealingly receives a check valve. The charging valve sealingly engages the housing bore via a sealing ring in one position and is pressure responsive to move toward a second position abutting the check valve to open communication between the inlet port and the accumulator. A stem is slidably carried in a passage in the check valve and the stem is received in a slot in the charging valve. An operator actuator is engageable with the stem to unseat one end of the stem from the check valve so that pressurized fluid from the accumulator is communicated to the pressure chamber. Moreover, the slot on the charging valve permits communication between the inlet port and the pressure chamber when the accumulator pressure is below the pressure at the inlet port and the operator actuator is unseating the stem from the check valve. In addition, the charging valve and housing bore include substantially parallel tapered surfaces that oppose frusto conical surfaces on the sealing ring that are substantially parallel to the tapered surfaces and between the housing bore and charging valve to seal the accumulator from the inlet port when the sealing ring is engaging the housing bore and the charging valve.

Title: Dual-circuit pressure control valve for hydraulic brake systems
IPC: B60T8/26
Filed: 1981-05-08
Abstract: In a dual-circuit pressure control valve for hydraulic brake systems, the control pistons disposed parallel to one another are each loaded by a first arm of an associated angular lever. Each of the levers have a second arm perpendicular to the first arm acted upon by a common tension spring disposed therebetween. The levers are located approximately in a plane defined by the axes of the control pistons. The tilting axes of the levers are disposed perpendicular to this plane and are disposed outside the axes of the control pistons. This results in a short overall length in both the axial and radial direction. In addition, a carrier device is provided which couples one of the control pistons with the lever of the other control piston after a small relative movement of the control pistons. This carrier device becomes effective upon failure of one brake circuit. The carrier device may be formed by extensions of the first arms which overlap one another with play.
