摘要： An infusion system includes a double action infusion pump. The pump includes a cylinder and a reciprocating piston received within the cylinder, the reciprocating piston separating a first pump chamber from a second pump chamber of the cylinder. A reciprocating motor is coupled with the reciprocating piston, and the first and second pump chambers alternate between filling and evacuating conditions with reciprocation of the reciprocating piston through operation of the reciprocating motor, and the speed of reciprocation is varied to provide a continuous output of fluid between the first and second pump chambers. A fluid source and a catheter are optionally coupled with the double action infusion pump. The catheter includes one or more infusion ports near a catheter distal portion, and the one or more infusion ports receive and expel the continuous output of fluid from the double action infusion pump.

摘要： The present invention includes: first and second tanks and each configured to store a fluid containing fine powder; a communication pipe through which the first and second tanks and communicate with each other; and a transfer portion configured to transfer the fluid stored in a desired one of the first and second tanks to the other tank. Each of the tanks and includes a first chamber and a second chamber that are separated by a deformable dividing wall. Each of the first chambers stores an incompressible fluid, and each of the second chambers stores the fluid having higher specific gravity and viscosity than the incompressible fluid. The second chambers of the first and second tanks communicate with each other through the communication pipe. When the incompressible fluid is supplied to the desired first chamber, the transfer portion can discharge the incompressible fluid from the other first chamber.

摘要： A cryogenic pump comprising a shaft disposed in a bearing. The shaft rotates with respect to the bearing housing, and the shaft includes an end with an angled face. The pump includes a drive at one end of the bearing housing. A tappet passage is formed through the drive housing. A pushrod housing connects to the drive housing. The pump includes a piston and a tappet sliding within the tappet passage. The tappet has a base end disposed within the tappet passage and a rod end extending below the tappet end of the drive housing. A fluid cavity is in the tappet passage between the piston and the tappet. The pump includes a pushrod connected to the tappet. The angled face of the shaft rotates and drives the piston toward the drive housing, pushing fluid within the fluid cavity against the tappet, driving the pushrod away from the drive housing.

摘要： A device for the drive control of a two-cylinder thick matter pump has a diverter which is arranged in a material charging container and a motor-driven hydraulic variable displacement pump, via which both the drive cylinders of the thick matter pump and the drive mechanism of the diverter are controlled. An adjusting throttle is arranged in a pressure line between the high-pressure outlet of the variable displacement pump and the drive cylinders of the thick matter pump. A control line which leads to an adjusting mechanism of the variable displacement pump is coupled back from the pressure line downstream of the adjusting throttle. A connecting line which leads to a supply connector of the diverter hydraulics and in which a fixedly adjusted throttle can be arranged is branched off from the pressure line upstream of the adjusting throttle.

摘要： A high-pressure pump having a high-pressure cylinder which has a vertically moving plunger fitted therein from the upper side thereof. The high-pressure cylinder has at least one opening in the bottommost portion thereof to allow a fluid to flow in or out of the high-pressure cylinder. A hydraulic cylinder for driving the plunger is provided on the top of the high-pressure cylinder. In addition, a migration preventing device is provided between the hydraulic cylinder and the high-pressure cylinder and in contact with the plunger driving shaft to prevent migration of a working fluid leaking out from the hydraulic cylinder to the surface of the plunger fitted in the high-pressure cylinder.
