Title: Air inlet valve for vacuum tank - has large opening to enable tank to be filled quickly with air without use of additional control equipment
Inventor: FUCHS WERNER KARL-HEINZ
IPC: F16K24/06
Filed: 1974-06-11
Abstract: The valve consists of a first chamber (3) which is connected via a non-return valve (6) to a second chamber (2). This second chamber is connected directly to the vacuum tank. A pipe line from the first chamber leads via a valve to the vacuum pump or other source of vacuum. The two chambers are separated by a membrane (4) to which a valve (9) is connected. This valve covers an opening which leads directly to atmosphere. The area of this valve is smaller than the area of the membrane. If the vacuum line is connected to atmosphere, a large force will be exerted on the membrane which will overcome the smaller force acting on the valve connected to the membrane and air can enter the tank directly through this valve.

Title: Self cancelling direction indicator switch - with asymmetric ratchets for lower cam release force than lever release
Inventor: ERDELITSCH HERBERT
IPC: B60Q5/00
Filed: 1974-08-12
Abstract: The ratchet assembly for the direction indicator switch has two spring loaded ratchet teeth (16, 17) whose upper surfaces are inclined in opposing directions. A fixed ratchet plate has sets of fixed ratchet teeth (11, 12, 13, 14) which engage the spring loaded ratchets with parallel sloping faces when the switch is moved to either setting. A relatively small manual force is required for this. To move the switch back to the null setting manually requires a larger force because the slopes of the ratchet teeth oppose the movement. The self cancelling cam (15) has sloping faces in two directions and engages the sloping faces of the spring loaded ratchets to push them free with a small force.

Patent DE-2611525-A1 (DE)
Title: Fine control tyre pressure valve - has closing spring lifted when test button pressed to expand indicator membrane
Inventor: DIETL HANS
IPC: B60C23/00
Filed: 1976-03-18
Abstract: The tyre pressure control valve has a vavle element (8) which seals the valve from inside the tyre, with the vavle stem extending into the control housing. The stem is normally held between two springs. One inner spring holds it in the closed position and an outer spring tends to open the valve, against the pressure of the tyre. The tyre pressure is tested by depressing a button to lift the closing spring out of contact with the element. The opening spring pressure is then balanced against the tyre pressure to open the valve if the tyre pressure falls below a set value. The tyre pressure is thus gauged against only one spring, which can thus be kept weaker than in conventional systems in which the opening spring acts against the combined force of the tyre pressure and the closing spring.
