A cab is installed on many modern cars, for lowering and raising which a special mechanism is responsible, equipped with a hydraulic drive directly from a separate pump. The latter is quite simple. Its basis is a body with a plunger pair. It also has a bushing. Under the plunger is a channel that opens into a cavity with several balls. One of the balls is pressed against the seat by means of a spring. The inlet ball lies on the seat. It can move freely along the channel.

The design of the driver cab tilt pump

Above the plunger on the body, there is a FEBI BILSTEIN brand Tilt Pump, driver cab. It provides a swinging support. Through the simplest hinge, the handle is connected to the plunger. The movement of the handle moves the plunger. He is also responsible for the operation of the entire pump. The oil tank is located on the side of the body. The tipping mechanism does not have a separate tank. Inside there is a suction filter with a safety valve. It allows oil to drain directly from the discharge cavity into the reservoir if the outlet valve is closed.
