摘要： A spherical puffing pump for an ice cream machine and an air inlet device thereof. The spherical puffing pump includes a spherical pump body, a clamping plate and an air inlet valve. A liquid feeding hole of the spherical pump body is connected to a milk slurry tank to feed milk slurry. The air inlet valve is connected to a channel of the liquid feeding hole to introduce air. A liquid discharging hole is connected to a liquid inlet of a refrigerating cylinder. A pump seat is fixed on the ice cream machine. An end portion of the pump seat protrudes from an inner wall of the tank. A cylinder of the spherical pump body is connected to the end portion through the clamping plate. A main shaft of the spherical pump body is connected to a motor shaft through a connecting shaft for power transmission. The puffing rate is adjusted according to the size of the air inlet hole and the rotating speed of the motor.

摘要： Disclosed are a hydrostatic pressure support and a spherical pump having the same. The hydrostatic pressure support is arranged between each of two parallel sides of a slipper and a sliding groove, and includes a first liquid flow channel, a second liquid flow channel, and a pressure-bearing groove. An inlet of the first liquid flow channel is communicated with one of two working chambers of the spherical pump, and an inlet of the second liquid flow channel is communicated with the other of the two working chambers. An outlet of the first liquid flow channel and an outlet the second liquid flow channel are respectively communicated with the pressure-bearing grooves provided on the two parallel sides of the slipper.

摘要： Disclosed are a micro electro-hydraulic linear actuator and a dexterous hand of an electro-hydraulic driving robot, comprising an actuator base, a spherical pump unit and a reciprocating piston mechanism encapsulated in a closed elastic leather bag. The actuator base is provided with a hydraulic cylinder and a cylinder liner, both of which are cylindrical chambers with an open at one end. An open end of the hydraulic cylinder is provided with an end cover of the hydraulic cylinder, an open end of the cylinder liner is provided with an end cover of the motor, the reciprocating piston mechanism is provided in the hydraulic cylinder, and the spherical pump and motor are integrated in the cylinder liner to form a spherical pump unit; the present application adopts a distributed hydraulic source as the driving force and does not need a directional valve.
