A multiliner for a ball nut, a ball nut and a ball screw assembly are provided. Methods of forming the multiliner are also provided. The multiliner includes return channels that are configured to prevent bearing balls from falling out of a retaining region in a radial direction. This allows bearing balls to travel past intermediate grooves formed in a cooperating threaded ball screw shaft.

A valve comprises a body having a first inlet, a second inlet, and an outlet. A shuttle is shiftable between: a first position permitting communication between the first inlet and the outlet and blocking communication between the second inlet and the outlet; and a second position permitting communication between the second inlet and the outlet and blocking communication between the first inlet and the outlet. One or more permanent magnets are positioned to bias the shuttle away from a neutral position between the first position and the second position, wherein the valve further comprises: one or more electromagnets positioned to, in at least one condition of energization, counter said bias.

Bi-stable changeover valve

A dispensing apparatus () comprises: a freezing cylinder (); a water flowpath (); a first controllable valve () along the water flowpath; a syrup flowpath (), merging with the water flowpath and proceeding as a water/syrup flowpath () to the freezing cylinder; and a second controllable valve () along the syrup flowpath. The first controllable valve and the second controllable valve each comprise: a valve body () having a cartridge compartment (), an inlet () to the cartridge compartment, and an outlet () from the cartridge compartment; and a valve cartridge (). The valve cartridge comprises: a cartridge body () mounted in the cartridge compartment; a valve element () carried by the cartridge body and shiftable between a first condition permitting communication between the inlet and the outlet and a second condition blocking communication between the inlet and the outlet; and a solenoid () carried by the cartridge body and coupled to the valve element to drive movement of the valve element.

A dispensing apparatus has: a freezing cylinder; a water flowpath; a first controllable valve along the water flowpath; a syrup flowpath; and a second controllable valve along the syrup flowpath. The flowpaths merge as a water/syrup flowpath to the freezing cylinder. The first controllable valve and the second controllable valve each have: a valve body having a cartridge compartment, an inlet to the cartridge compartment, and an outlet from the cartridge compartment; and a valve cartridge. The valve cartridge has: a cartridge body mounted in the cartridge compartment; a valve element carried by the cartridge body; and a solenoid carried by the cartridge body and coupled to the valve element to drive movement of the valve element. The valve element is shiftable between a first condition permitting communication between the inlet and the outlet and a second condition blocking communication between the inlet and the outlet.

A seal assembly including at least one conduit configured to allow a medium to flow therethrough, an annular retaining means operably coupled to the conduit, and an annular resilient seal member disposed in the annular retaining means. A method of sealing a dispensing system containing a food product creating a food product pressure, wherein the dispensing systems includes a drive shaft operably coupled to a seal assembly, the seal assembly including an annular resilient seal member disposed in an annular retaining member, the annular retaining member being operably coupled to at least one conduit, the method including the steps of: dispensing a medium through the at least one conduit to enter the annular resilient seal member to create a seal pressure greater than or equal to the food product pressure.

A refrigeration system both cools and heats frozen dessert mix in at least two hoppers and at least two freezing cylinders. A liquid line solenoid valve at the inlet of each of the hoppers and the freezing cylinders controls the flow of refrigerant from the condenser. A hot gas solenoid valve at the inlet of each of the hoppers and the freezing cylinders controls the flow of hot refrigerant from the compressor. The system further includes a hot gas bypass valve that is opened when only the hoppers are being cooled to provide additional compressor load. An EPR valve proximate to the hopper discharges varies the temperature of the refrigerant exchanging heat with the mix in the hoppers. A CPR valve controls the inlet pressure of the compressor by reducing the amount of hot refrigerant flowing into the compressor suction. A TREV valve injects liquid refrigerant to the compressor suction to control excessive compressor discharge during the cool cycle.

Hot gas heat treatment system

A hot gas heat treat system is employed to cool mix in a hopper and a freezing cylinder and to heat the mix for pasteurization. A hopper liquid line solenoid valve at the inlet of the hopper and a cylinder liquid line solenoid valve at the inlet of the freezing cylinder each control the flow of refrigerant to the expansion valves which further control the flow of refrigerant that flows around the hopper and the freezing cylinder, respectively. A hopper hot gas solenoid valve at the inlet of the hopper and a cylinder hot gas solenoid valve at the inlet of the freezing cylinder control the flow of refrigerant from the compressor that flows around the hopper and the freezing cylinder. The system further includes a hot gas bypass valve that is opened when only the hopper is being cooled to provide additional load to the compressor. An EPR valve is positioned proximate to the hopper discharge to vary the temperature of the refrigerant exchanging heat with the hopper. A CPR valve is employed to control the inlet pressure of the compressor by reducing the amount of hot refrigerant flowing into the compressor suction. The system further includes a TREV valve to allow for liquid refrigerant injection to the compressor suction to control excessive compressor discharge during the cool cycle.
