摘要： A bypass valve provides an elongated valve body defining a bore and a longitudinal axis. A first pair of axially spaced ports are attached to the valve body and include a service inlet port and a service outlet port. In addition, a second pair of axially spaced ports are attached to the valve body and include a valve inlet port and a valve outlet port. The bypass valve also has an elongated spool with an axis of rotation coinciding with the longitudinal axis while positioned to rotate in the bore between a service position and a bypass position. As part of the spool, a first curved land defines an outlet passage from the valve inlet port to the service outlet port, and a second curved land axially spaced from the first curved land defines an inlet passage from the service inlet port to the valve outlet port. The curved lands define the inlet and outlet passages so that fluid passing through the valve passes directly through a generally central area of the bore without diversion or obstruction by a central axial shaft. A bypass passage is located on the spool opposite the curved lands and is configured to provide fluid communication from the service inlet port to the service outlet port.

摘要： The invention relates to a thin sheet material which can be bonded for the production of separator pockets for lead accumulators in which, in particular, the positive plates of the lead accumulators provided with a web covering are jacketed. It is the objective to optimize the production of the separator pockets and the web covering of the plates and to obtain a better utilization of the positive mass. This objective is met by a web covering which is directly applied to the sheet material for the production of the separator pockets and has an area extension which is smaller than the inside area of the sheet material defined by the provided bonding seams of the separator pocket wherein the web covering preferably consists of an electrically conductive material.

摘要： A light attachment that can be readily mounted on a variety of tools and tool support fixtures and other support structures includes a light portion supported on a mounting portion by a flexible gooseneck cable. The mounting portion includes a housing that defines a male-female attachment element configured to slidingly mate with a complementary attachment element formed on the body of the power tool. In a preferred embodiment, the attachment element has a dovetail shape for sliding engagement within a complementary shaped notch in the body of the tool. The housing contains a power source for the light portion. The light portion incorporates an on-off switch that is actuated by rotating a component that is threadedly engaged within the housing. The housing supports a printed circuit board to which the power supply wires are attached. The circuit board also carries a spring contact switch element that completes an electrical circuit to energize the light portion when the spring contact is pressed against the circuit board. Power is supplied through the circuit board and switch to an LED light element. The LED is disposed within the housing so that the rotatable component can push the base of the LED into the spring switch to close the electrical circuit.

摘要： A water conditioner valve includes a main housing configured for providing fluid communication between a plurality of locations, and having first and second valve chambers, a main piston mounted for reciprocal movement in the first valve chamber and having a main piston rod attached thereto, the main piston rod provided with a main cam follower; a supplemental piston mounted for reciprocal movement in the second valve chamber and having a piston rod attached thereto, the supplemental piston rod provided with a supplemental cam follower; the valve also having a cam member having an axis of rotation, a first cam track for receiving the main cam follower, and a second track for receiving the supplemental cam follower, the cam tracks being constructed and arranged on the cam member so that rotation of the cam member will cause movement of the pistons along a linear axis which is parallel to the axis of the cam member for controlling the relative positions of the pistons in the respective chambers to obtain the desired fluid flow. When used as a valve in a water conditioning apparatus with a regeneration cycle, the supplemental piston is a brine piston which controls eduction and fast rinse steps.
