A solenoid valve includes a housing, a bobbin and an armature. The bobbin is received at least partially within the housing and has and internal passage and a body about which a coil is provided. The armature is moveable relative to a valve seat and the valve includes an armature stop received in the internal passage with a press-fit so that it is engaged by the armature in one position of the armature to limit movement of the armature away from the valve seat. The valve also has a biasing member located at least partially between the armature and the armature stop, the armature has a reduced diameter portion received at least partially within the biasing member, and wherein the reduced diameter portion engages the armature stop in the open position of the valve.

A pilot device for a hydraulic directional valve includes a displacement sensor, a pilot valve, an actuating device, a coil assembly, and a circuit board. The displacement sensor has a sensor axis and the pilot valve has a valve axis. The valve axis and the sensor axis are arranged substantially parallel to one another so as to lie in a reference plane. The actuating device and the coil assembly are arranged adjacent to one another. The circuit board is arranged parallel to the reference plane. In each case, to establish an electrical contact, the coil assembly, the actuating device, and an electrical plug connection are either soldered directly to the circuit board or are in breakable electrical contact with a respectively associated, rigid contact assembly. The contact assembly is soldered directly to the circuit board.

A sensor assembly for controlling a flow of water through a faucet includes a shank and a head. The shank is configured to pass through an aperture in a wall and terminates at a flange at a first end of the shank. The head is configured to be coupled to the shank. The head includes a base, a top portion, and circuitry. The base has a first side configured to be supported by a first side of the wall and a second side configured to interface with a first side of the flange. The base includes an opening configured to receive the flange and a hole configured to receive a portion of the shank. The circuitry is configured to be positioned between the cover and a second side of the flange opposite the first side of the flange. The circuitry interfaces with the second side of the flange.

A solenoid valve includes a valve body extending along an axis between a first end and a second end and defining a fluid passage, a valve member disposed at least partially in the fluid passage, and a solenoid actuator coupled to the valve body. The solenoid actuator includes a flux core having a proximal core end adjacent to the valve body and a distal core end spaced from the proximal core end. At least one of the proximal and distal core ends defining a bore. The solenoid actuator also includes a bobbin extending along the axis and having a proximal bobbin end adjacent to the valve body and a distal bobbin end spaced from the proximal bobbin end, and at least one protrusion extending from at least one of the proximal and distal bobbin ends of the bobbin and through the bore to couple the bobbin to the flux core.

A linear solenoid valve has a spring member and a spring load adjusting member, which is screwed into a sleeve member of the linear solenoid valve in order to adjust a spring load of the spring member. The sleeve member has a female screw portion and a swaged-claw forming portion is formed at an axial end surface of the female screw portion. Multiple swaging punches are prepared, each of which has a punching tooth portion of a punching portion. A punching area of the punching tooth portion differs from the swaging punch to the swaging punch. One of the multiple swaging punches is selected depending on a press-direction distance between the swaged-claw forming portion and an axial end surface of the adjust screw member. When the press-direction distance is smaller than a predetermined distance range, the swaging punch having a larger punching area for the punching tooth portion is selected, wherein the punching area is larger than a punching area of another swaging punch which is selected when the press-direction distance is larger than the predetermined distance range.

A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.
