A pump and valve combination for bladder adjustment is revealed and including a fluid supply member, a valve member and a bypass line. The fluid supply member includes a head end and a tail end. A bottom cover is disposed on the tail end and the fluid supply member provides fluid to the bottom cover through the tail end. The valve member is arranged at the head end and communicating with bladders. The valve member includes a valve cap fixed on the head end, a solenoid operated directional control valve, and an air supply tube. Two ends of the bypass line are connected to the bottom cover and an air input end of the air supply tube, respectively. An input portion and an output portion of the solenoid operated directional control valve are connected to an air output end of the air supply tube and the bladder respectively.

Pump and valve combination for bladder adjustment

A pneumatic pump having an overpressure protection valve having a gasket and spring that includes a diaphragm carrier, a diaphragm member, a valve base, a valve, a cap, a driving device and an overpressure protection valve is revealed. A pump chamber is formed between the diaphragm member and the valve base. The overpressure protection valve having a spring and a gasket. A discharge channel, an air-flow channel and a backflow channel are formed among the pump chamber, the valve base, the valve and the cap. The discharge channel, the overpressure protection valve and the spring chamber are separated. The gasket is disposed between the air-flow channel and the backflow channel for closing the air-flow channel normally. The driving device drives the diaphragm member for discharging air from the pump chamber through the discharge channel.
