Patent CA-2790754-A1 (CA)
Inventor: MEHRA RAKESH J
IPC: B67D1/12
Filed: 2012-09-24
Abstract: Liquid flow balancer, with a ball/ balls and wedges, by placing one or series of same size or different sizes balls inside a tubing/ housing unit.  This specific volume of the ball/ balls will reduce the volume and speed of the medium that will flow through this housing unit. The flow rate cannot be changed since the amount of balls control the mass flow rate, hence it is a fixed flow rate balancer.  The housing unit (2) which houses the ball/ balls (4) is designed to reduce the volume and mass flow rate of the medium flowing through the tubing/ housing (2). Wedges (3) are designed to prevent the ball/ balls (4) from blocking the opening of the splicer (1), which maintains the inside diameter of the tubing/    housing (2). The splicer (1) also aids in extension of the tubing/ housing (2).  Another option of using hose nipple* (5), to connect the flow balancer to a specific piece of equipment used called keg coupler.

Abstract: A pump has a boltless cover that is held on the end of a housing of the pump by only a compressed ring between the cover and the housing. The pump has a flangeless valve plate, meaning that the valve plate has no flange through which bolts that secure the head to the pump extend. The pump has eccentrics and pistons that all have holes in them so that the pistons at opposite ends of the pump can be assembled to the shaft of the motor 180° out of phase. The pump further has a monolithic head that includes the two head members of the pump and the tube that connects them also has an integrally formed port. The pump is supported by elastomeric tubular members from its ports. The pump has a push-in fitting that can be pushed into a hole in a member such as the head, the housing or the base so that once pushed in, a ring around the fitting expands outwardly behind an edge of the body to trap the fitting in the opening.
